How to Identify Dirty Fuel Injectors

A bad or dirty fuel injector can significantly impact your vehicle processes, mainly your gas mileage and engine performance. This is because they play a vital role in delivering fuel to your engine to achieve optimum combustion. Achieving a desirable gas mileage may become a challenge with a faulty fuel injector. This is why it's necessary to take your car into our shop for regular maintenance, so our certified mechanics can spot these signs early and repair your fuel injectors. 


A worn fuel injector can usually be repaired by a thorough cleaning of the fuel injection system. A minor malfunction in one of your fuel injectors can impact the entire operation. Therefore, if you experience the following warning symptoms, you should take your car to The Car and Truck Guys for a fuel cleaning service!

Engine Stalling 

If your car or truck often sputters and rocks when you are idling, this is one major sign that your fuel injector is the culprit. Engine stalls occur because of fuel inconsistency, and you may have to restart your car from time to time.

Engine Misfires

If your engine receives dirty fuel from your injectors, your motor may misfire. 

Poor Fuel Economy

Gas mileage is something that most drivers care about and constantly monitor. If you see a drop in your MPG, it might be time for a fuel system inspection. Clean fuel injectors should correct your gas mileage and get you the efficiency that your car needs.

Laggy Acceleration or Wild RPM Needle

Slow or sluggish acceleration is a sign of dirty fuel injectors. In addition to the problems with acceleration, your engine RPM may fluctuate rapidly due to the inconsistency in fuel delivery.

Check Engine Light On

Lastly, a malfunctioning fuel injector may signal the car's computer system and trigger the check engine warning light to come on. To have your check engine light diagnosed and reset, please visit The Car and Truck Guys.
