What is a Fuel Injection Flush?

A fuel injector flush is performed to clean out the build-up that occurs on your car’s fuel injectors and fuel system. It flushes out the fuel system, making your vehicle run better and more efficiently.

Why is a Fuel Injection Flush Important?

By cleaning the build-up in your car’s fuel system, a fuel injector flush provides many benefits to your vehicle, including:

  • Improves your gas mileage, thus, saving you money
  • It helps to reduce emissions and reduces your carbon footprint
  • It can also increase the life of your vehicle

How Does a Fuel Injection Flush Impact Gas Mileage?

A fuel injector flush can really help your gas mileage as clogged fuel injectors can cause a lot of problems.

With clogged fuel injectors, less gas is able to get through, which affects how your vehicle drives. Some injectors may let more gas through than others, leading to an imbalance. The longer this goes on, the worse it gets. The computer in your vehicle will try to adjust by using more fuel, worsening your gas mileage. A fuel injector flush clears this build-up, balancing the fuel system and providing you with better gas mileage.

Job of an Engine Block

The engine block is important in the functioning of the car by supporting components of the engine. It transfers heat from friction to the coolant and atmosphere and supports the lubrication circuit and auxiliary devices such as the alternator. Its significance brings the need for drivers to regularly maintain their vehicles to prevent destruction to internal parts. Damage to parts of the engine can be caused by insufficient oil and overheating.

Regular inspection and maintenance of the engine block helps in ensuring the car engine operates normally and efficiently. Maintenance is crucial to the block’s lifespan and to maintain optimal performance and economical usage of fuel.

Components of an Engine Block

  1. Cylinders. These are the spaces where pistons travel. They are large in size and have precisely formed holes to create a seal with the piston. The size and number of cylinders measures the power and size of an engine.
  2. Oil Passages or Galleries. These allow oil to reach the cylinder head and the crankshaft.
  3. Deck. This is the top surface of the block where the head of the cylinder sits.
  4. Crankcase. This houses the crankshaft and is found at the bottom of modern engine blocks.

Other components include engine mounts, core plugs, coolant, ancillary mountings, and faults.

Common Problems with an Engine Block

The engine block is designed to last forever but sometimes things go wrong. Some of the common problems with the engine block are external coolant leaks, cracked cylinders, and a porous engine block. The importance of an engine block brings the need for regular inspection and maintenance.

Why Your Car Needs a Tune Up?

If your vehicle is experiencing a drivability problem, it’s getting hard to start, fuel mileage has dropped, stalling and hesitating, knocking or failing to run on same zip and power, or even failing on emission tests, then it needs an engine tune up. For most cars, tune-up maintenance is recommended after your car reaches 30 thousand miles.

Engine Tune Up: What We Do

We first perform tune-up checks to establish your engines overall condition, and these include:

  • Battery Voltage – Cars today have multiple on-board electronics that require constant charging.
  • Power Balance or Dynamic Compression – To identify mechanical problems that can negatively affect engine performance.
  • Engine Vacuum – To establish probable air leaks or exhaust restrictions.
  • Scanning Fault Codes – To establish if fault codes are present for immediate diagnosis and elimination.
  • Verify Idle Speed – To establish probable ISC motor problems.
  • Check Ignition Timing – To establish any computer or sensor problems.
  • Visual Inspections – To establish all engine fluids are at the proper level and conditions acceptable.

What We Replace After Checks

Upon detecting major faults, we replace following items to maximize engine performance:

  • Spark Plugs – These need periodic replacements as electrodes wear-out due to constant firing – recommended after 30,000 miles of operation.
  • Rotor or Distributor Cap if need be.
  • Fuel Filter: other parts on a need be basis – oxygen sensors, belts, hoses, and fluids.

At Custom Complete Automotive, we strive to keep your car running as smoothly and efficiently as possible. To schedule a tune-up to determine if your engine is performing at optimal level, or for more information about our services, contact us today for reliable service you can trust!

Diesel vs Gasoline Engines

When looking to buy a car, there are many different things to consider. The make and model, car versus truck, what color to choose, and what features you want are all things to take into account. But have you considered the type of engine your potential new vehicle will have?

Both diesel and gasoline engines are internal combustion engines, which means that fuel and air are mixed once they are in the engine and then combustion occurs, sparking the transmission to turn the wheels. It’s a complicated process with amazing results – a car we can drive to get where we need to go.

diesel and gasoline gas pumps

What Makes them Different?

The difference in the engines is how the fuel is ignited. While both engines convert fuel into energy through small combustions, the way these occur is where they differ. With gasoline engines, the inclusion of spark plugs ignites the compressed air after the fuel and air are mixed, creating the combustion. With diesel engines, the air is compressed first and is heated up so that when the fuel is added, it combusts.

Pros and Cons of Diesel Engines

There are a few factors to consider when comparing the engines.


  • Diesel engines typically get better mileage and are more efficient than gasoline engines. A gallon of diesel has 30% more energy than gasoline and is a thick, syrupy substance compared to watery gasoline.
  • Diesel gives off more torque, creating a faster acceleration, helping it gain the advantage in mileage and power.
  • Since a diesel engines are built to be tougher, they don’t need as much maintenance or major repairs and are often more reliable.
  • Diesel engines are now typically more environmentally conscious than gasoline engines.


  • Diesel engines can take longer to ignite in colder weather since they rely on heated air to create the combustion.
  • Diesel vehicles do tend to be more expensive, both for the fuel and the car itself. They can sometimes also cost more to insure.
  • Depending on how you care for your vehicle, repairs can also be more costly.

Maintenance Costs

Both engines will require maintenance. Maintenance is usually easier and cheaper when it comes to gasoline engines. A ton of regular maintenance isn’t required for a diesel engine, other than regular oil and filter changes, as they are much sturdier than gasoline engines. However, when they do need attention, the complicated nature of a diesel engine can make it a more costly repair.

So Which Engine is Better for You?

Determining which engine is better for you will ultimately come down to preference and there is no right answer. But rest assured, no matter what kind of engine you choose, our employees at Custom Complete Automotive are here to help with all your maintenance needs.

Fuel Injection Service Explained

Every car engine has a fuel system that is comprised of a fuel filter, a pump, and injectors. During a fuel injection service, your mechanic will typically inspect all connections, the fuel and vacuum lines, the fuel rail, and the pressure regulator. They will then clean the fuel injectors and throttle body air intake. Afterward, they’ll pressure test the fuel pump and system and then decarbonize other parts of the system like the exhaust valves. When all is said and done, they will run exhaust emissions test to make sure the system is working properly again.

Why You Need It

As you drive your car, environmental wear and tear like dirt, carbon, and varnish can build up in your fuel system. This can damage part or all of your system, which can then lead to possible damage to other parts of your engine.

The Benefits Go Beyond Your Car

Getting your fuel injection system serviced helps more than just your car. While it does help cut back on gas usage and extend the life of your vehicle, it can also prevent your warranty from being voided. Fuel injection service can save you money in the long run, reduce the number of breakdowns your car experiences, and increase the safety of your vehicle for you and others on the road. But perhaps one of the best, most welcomed benefits is that it is helpful to the environment by reducing or eliminating air pollution.

When to Get a Fuel Injection Service

You’ll want to look at your user manual, as each car is different, but it is usually recommended that you get your fuel system serviced about every 25,000 miles. But, if your vehicle is experiencing any of the following, you’ll want to see your mechanic sooner.

  • Poor performance overall
  • A rough idle or lurching
  • Repeated stalling
  • Poor acceleration
  • Engine pinging
  • Poor fuel mileage

Why You Shouldn’t Ignore Your Check Engine Light

It’s easy to ignore the check engine light when it comes on in a vehicle, especially when life is busy. However, to keep your vehicle running at peak performance and avoid any safety issues, it’s important to check for any problems soon after the light appears.

What the Check Engine Light Means

A check engine light is your vehicle’s way of communicating that something isn’t working right. Modern vehicles have a computer system within them that continually monitors for issues. The check engine light turns on when an issue is detected. The check engine light might come on if the gas cap is loose, for example. It can also indicate something more serious, such as a misfiring engine. A blinking light typically indicates a more emergent situation, while a steady light indicates something of a lower priority.

When Maintenance is Needed

Whenever the check engine light appears, it’s important to have the vehicle inspected. Even if it seems to be running smoothly, a vehicle might have a potentially costly problem brewing. Though there may be something simple wrong, such as a malfunctioning sensor, it’s still important to fix. An unaddressed problem can potentially result in a more serious issue or even compromise the safety of the vehicle.

Diagnosing the Problem

An auto technician will use an electronic system to diagnose the problem. Along with turning on the check engine light, the computer in your vehicle will store a code that identifies the source of a problem. The code can be read with a special electronic scan tool or a diagnostic computer. From there, the technician can better pinpoint the issue and begin resolving it. Whether it’s something simple like a broken oxygen sensor or something more serious like a faulty catalytic converter, a diagnosis provides peace of mind and the ability to address the problem.

When the check engine light appears, don’t ignore it! Vehicle maintenance can prevent expensive problems down the road. For more information or to schedule an appointment, contact Custom Complete Automotive for friendly, reliable service!

The Mechanics Behind a Fast Car

When it comes to a fast car, horsepower is only a small part of the equation. Fast cars use a whole slew of other components to make them well-rounded sporty machines. From the transmission to the tires and everything in between, a properly fast car requires a myriad of specially tuned components that are well-maintained.

Maintaining Power

To put it simply, a car engine is a complex air pump. Air is sucked in and mixed with gasoline, ignited by a spark plug, then expelled through an exhaust pipe system. The more air in an engine, the more power you’ll get out of it. However, things begin to get complicated when you look at the many factors and components that go into the seemingly simple process of breathing air into an engine.

Breathing Air and Lighting It on Fire

At the front of the engine is an air filter that keeps abrasive dirt and debris out of your engine while letting clean air flow through. A dirty, worn-out filter will rob even the fastest cars of their lifeblood so it’s important to keep your air filter clean and replace periodically. You can even opt for a high-flow aftermarket filter to let more air in and produce a bit more power.

Then there’s the ignition system, namely the spark plugs and electrical components that power them. Faulty plugs or wires will produce inadequate or inconsistent sparks in the cylinders and make your engine run extremely rough, robbing it of power, smoothness, and reliability.

Sealing Everything Up

From the head gasket to the rear muffler flanges, your engine uses a slew of rubberized seals to keep everything airtight. Leaky engine seals will make your engine run terribly while letting vital fluids, like oil, escape. Leaky intake and exhaust seals will decrease power by creating turbulent airflow into and out of the engine. Keeping your car running fast and smooth requires diligent maintenance of all the seals throughout the entire power train.

Handling Components

Speed isn’t all about straight-line acceleration. Handling and stopping power are just as important. Worn-out transmission components will keep your engine from driving your wheels properly and rob you of acceleration. Broken suspension and chassis components will cause your car to poorly handle corners and create an uncomfortable ride. To keep your car truly fast and reliable, properly maintain all of these components so that they work in unison to make your car a well-rounded speed machine.

If you’re not mechanically inclined, it’s important to have expert mechanics on your side to ensure your car is in tip-top shape. To keep your car running fast and smooth for as long as possible, contact us today!

Get to Know Your Engine Block

At Custom Complete Automotive, we’re not above playing with blocks – most importantly, engine blocks! The engine block houses the cylinder and other essential parts of the internal combustion engine, including the crankshaft, coolant and lubrication passages, the water cooling jacket, and other various pistons inside the cylinder. The cylinder block may be split up into an upper and lower block depending on your engine. This block is built to be powerful and sturdy, because it essentially holds your vehicle together. If your engine block stops working, your car will not function!

vehicle engine being repaired

The engine block is responsible for a variety of operations: placing and distributing fluids, maintaining the accuracy of the main components within the block, and, perhaps most importantly, conducting heat. If the cylinder block is prevented from conducting heat correctly, this can cause it to seize up, causing engine failure. Regular inspection and maintenance of this piece is important for the overall lifespan of your vehicle.

While the engine block itself is a strong hunk of metal, it is not immune to problems. There are some common things to be cautious about as you put more miles on your car, and thus more wear on the engine block.

  • Cracked cylinder. Over time, the smooth cylinder walls will become warn, causing them to crack in some cases. This often results in your cylinders misfiring, developing a lot of damage. In extremely bad cases, a cracked cylinder could be terminal for your engine block.
  • Coolant and oil leaks. Sometimes a minor crack in the engine block or a loose plug can cause fluids to leak out of your car. It is dangerous to drive for too long without addressing this problem.
  • Poorly cast block. Your engine block could have been molded incorrectly during the manufacturing process, causing the casing to become porous.

Engine problems can be a headache, so make sure you keep up proper care and regular inspections. If you think your vehicle’s engine needs repair or you have any other questions or issues, contact us today for a fast, friendly fix for your vehicle.
