5 Common Signs of Dirty Fuel Injectors

July 3, 2021

Dirty fuel injectors can result in some tricky situations. Your fuel injectors work with your fuel filter and pump to simultaneously provide the engine with an adequate amount of clean fuel. Over time the fuel injector quality deteriorates. How do you know when it's time to have the fuel injectors cleaned? Below are the five most common symptoms that indicate you need fuel injector repair. 


POOR GAS MILEAGE


If you've had your car for a long time, then you know how far you can go on a gallon of fuel. If you notice your MPG going down, it means the engine is not performing optimally, and one reason could be a faulty injection system. It is important to note that many other problems can lead to poor gas mileage. It is best to take your car into our shop, so one of our expert technicians can correctly diagnose the problem.


CAR ENGINE MISFIRES


In severe cases, dirty fuel injectors can cause your engine to misfire. The misfire occurs when there's difficulty with the air and fuel mixture entering the engine. This problem will usually cause the car to vibrate. You might even hear a jerk and pop sound. 


ROUGH IDLING WHEN YOU COME TO A STOP


When your vehicle shakes and sputters when you are stuck in traffic or coming up to a red light, it may imply that your fuel injector is dirty. Rough idling happens when your RPMs (revolutions per minute) change unexpectedly, even if your foot isn't on the pedal.


YOUR CAR CANNOT START


We all know your car needs gasoline to start. A bad fuel injector can't deliver fuel into the cylinders and power the engine. If your tank has gas and your engine doesn't run, then your injector could be the culprit.


CHECK ENGINE LIGHT COMES ON


The check engine light will come on the dashboard if there isn't enough gas getting to the engine to complete the combustion process. In some cases, there may be too much fuel in the machine as well.

When you're heading off the pavement and into the dirt, rocks, or sand, one of the most important adjustments you can make to your vehicle is tire pressure. While highway tire pressure is optimized for fuel economy and tread life, off-road tire pressure serves a very different purpose.
