EFI Injectors Clean & Tune-up at HAC Rockhampton

Your car’s fuel filter, pump, and EFI injectors are all part of an interconnected under-the-hood system that feeds fuel to the engine via the Injectors.

EFI Injectors Need to be serviced From Time to Time

EFI injectors become fouled over time, this varies depending on which fuel you use and the way you use your vehicle. You may be tempted to try petrol additives which claim to clean the EFI injectors - it doesn't!

Does your vehicle have poor performance, poor fuel mileage, or rough idling? It either has a severe case of the Mondays or, more likely, some dirty fuel injectors.

Spotting the signs of dirty fuel injectors and investing in a professional cleaning process can help you smooth out your rough ride and get back to care-free economical cruising. You always get more and you pay less at Highway Auto Rockhampton.


Fuel Injector Basics

This might be the first time you’ve heard of fuel injectors, and that’s okay. Your car’s fuel filter, pump, and injectors are all part of an interconnected (though unseen) under-the-hood system. Together, the filter, pump, and injectors ensure your engine receives the correct mixture of fuel and air.

Here’s a general idea of how the whole fuel system works:

  1. Your car’s fuel pump delivers fuel to the EFI fuel injector.

  2. The fuel injector injects/sprays fuel into the intake manifold at a very precise angle.

  3. Within the intake manifold, air and fuel mix.

  4. The air-fuel mixture is compressed in the combustion chamber, igniting the chemical reaction required to power your engine.

Dirty Fuel Injector Symptoms

Knowing the complicated dance that goes on in your fuel injection system, it’s easy to see how bad or dirty fuel injectors can throw a wrench in your engine!

Here are a few signs there might be something wrong with your fuel injectors.

1. The Engine Misfires Dirty fuel injectors may cause your vehicle’s engine to misfire. This problem makes the motor feel as though it is sputtering — sending vibrations through the car. Such misfires can happen when a fuel injector problem mixes up the delicate balance between fuel and air entering the engine.

2. Idling Gets Rough Does your vehicle sputter and shake when you’re at a stop sign or sitting in traffic? It’s telling you that there may be dirty fuel injectors at work.

Typically, “rough idling” is characterised by varying revolutions per minute (RPMs), even when you have your foot off the pedal. Often, rough idling is accompanied by engine stalling — a sudden decrease in RPMs and engine noise that feels like running out of fuel on a hill.

Dirty fuel injectors are only one of several engine problems that can result in rough idling and engine stalling. If you notice these issues in your car, come in for a Complete Vehicle Inspection. Our expert technicians will get to the bottom of the problem and recommend a fuel system cleaning if needed.

3. Your fuel mileage has crashed Well-performing fuel injectors help your vehicle get the kind of fuel mileage that manufacturers promote. While a variety of engine issues can cause you to stop by your local petrol station more often, lousy fuel mileage could be a signal that something is wrong with your fuel injectors.

4. The RPM Needle Starts to Dance Typically, you control what your car’s dash gauges do. When you drive a lot, the fuel needle moves from “F” to “E.” When you accelerate, the speedometer moves from “0” to “60.” What do dirty fuel injectors do? They can cause the needle on the tachometer — the gauge that displays the vehicle’s RPM — to move unpredictably. You may notice the needle moves unprompted, indicating changes in RPM when your car isn’t switching gears.

5. Your Car Won’t Start Fuel injectors deliver fuel to the appropriate cylinders. That’s Job #1. And when Job #1 isn’t getting done, your engine won’t receive its crucial combination of air and fuel. When the ratio of air and fuel in your engine is off, your motor may not generate the combustion it needs to operate.

It’s rare, but in some cases, fuel injector issues can lead to engine failure that prevents your car from starting. It’s also possible that your car won’t start because, um, you forgot to put fuel in it. (It happens to all of us!) Unfortunately, running out of fuel can also lead to fuel injector issues.

Why Is My Car Sputtering When I Step On The Gas?

If your car sputters when you step on the gas, it’s crying for help.

A sputtering car might mean you’re about to run out of fuel, or it could point to something more serious like an issue in the fuel or exhaust system, including dirty or worn-out parts.

Follow along as we break down some possible explanations for engine sputtering and share with you why it’s so important to fix the problem ASAP.

Brake Service & Repair You Can Trust


Explanation #1: A Problem in the Fuel System

One of the most common causes of a sputtering engine is an issue with the vehicle’s fuel system—the filter, pump, and injectors. These three critical components work together to ensure fuel flows smoothly from the fuel tank to your engine’s fuel injectors, and then pumps into the engine evenly. This process produces the perfect mixture of fuel and air, which generates the combustion that powers your vehicle. Since the fuel filter, pump, and injectors work together as part of one interconnected system, dirt and debris need only clog one part to cause the others to fail. This can lead to poor engine performance or even complete engine failure.

To better avoid such troubles, Highway Auto Care Rockhampton recommends a once-a-year cleaning of your vehicle’s fuel system. Be sure to check your owner’s manual to determine whether an annual cleaning is sufficient, or whether your vehicle needs the service more frequently. One of our specialist technicians is ready to detect and fix any fuel system issues your vehicle may be experiencing.

Explanation #2: Worn Out Spark Plugs

Sputtering could also be a sign that your vehicle needs new spark plugs, which are among the most critical parts of your engine. The small-but-mighty spark plugs “spark” the air and fuel mixture in the engine, sending power surging through your vehicle. If they’re dirty or otherwise not working well, you might eventually wind up being unable to even start your vehicle.

As part of Highway Auto Care’s tune-up and engine service, one of our highly qualified technicians can determine whether the spark plugs are contributing to your vehicle’s sputtering engine and replace them if needed.
