Best Auto Repair News & Updates

Fuel injectors are critical components in your car’s engine. They are responsible for supplying the fuel and delivering it at the correct time to guarantee proper combustion. Over time, the fuel injectors can get clogged leading to a lean air to fuel ratio. Keeping current on your regular maintenance will help to prevent fuel injector issues.

What are fuel injectors?

Fuel injectors spray fuel into the engine at a precise angle. This fuel mixes with air, so your car produces the best possible combustion. If the angle, pressure, or spray pattern isn’t correct there will be an issue with how well your engine runs.

How does the fuel injector work?

The fuel injector regulates the amount of fuel injected into the combustion chamber. Fuel is pumped to the injector by the fuel pump. This fuel is then injected into the intake manifold, where fuel and air are mixed. This mixture is then compressed in the combustion chamber where it is ignited to provide you with the horsepower you demand.

Symptoms of a Malfunctioning Fuel Injector

Over time, fuel injectors need to be replaced, as they will become clogged. When they clog, there will be noticeable symptoms that you will experience. Some symptoms include:

• Reduced Fuel Economy: A malfunctioning fuel injector can cause your car to burn more fuel. This will lead to reduced fuel economy. It is always a good idea to keep track of your gas mileage, so you know when it begins to burn more fuel than normal.
• Fuel Leak: You should not be able to smell fuel when driving your car. If you can, you probably have a fuel leak. Watch for puddles under your car after it has been sitting for a while.
• Idles Roughly: Clogged fuel injectors can cause your car to idle roughly. If you notice your car does not run as smoothly as it once did, the injectors may not be providing the correct amount of fuel.
• Engine Stalls: When there is a lack of fuel caused by a malfunctioning fuel injector your car can stall.
• Car Will Not Start: The fuel injectors must be able to deliver the correct amount of gas to get the appropriate combustion. If the fuel is not delivered, your car won’t start.
• Misfires: When the fuel injector does not deliver the correct amount of fuel, the air to fuel ratio will be wrong. This improper mixture can cause a misfire.
• Sputtering Engine: When the fuel injectors are dirty, you can experience engine vibrations. This is due to the improper air to fuel ratio.
• Erratic RPM Needle: Dirty fuel injectors can cause your tachometer to act erratically.
• Failed Emissions Test: When the fuel injector has malfunctioned, your car is producing harmful emissions. These emissions are released through the exhaust system.
• Check Engine Warning Light: When your check engine light is triggered, have your car diagnosed right away. There are many different issues that can cause the light to come on. Some are minor, while others are major.

How to Maintain Your Fuel Injectors

The fuel system needs to be maintained just like every other part of your car. To maintain your fuel system and extend its life, follow these tips.

Do not let your gas tank run empty. It should never get under a quarter of a tank. Also, the general rule is to have the fuel filter replaced every 2 years or every 24,000 miles. However, all vehicles are different. Check your owner’s manual to see when you should replace your fuel filter. Last, have your fuel injection system cleaned every 30,000 miles.
