Most vehicles manufactured since the 1980s and newer come with advanced electronic fuel injection engines. A primary part of this complex system is the fuel injector.

You might never have experienced a problem with your fuel injectors before, but sometimes they do get dirty and clogged. If you do not address it, the fuel injector might fail and require replacement.

Here, your trusted mechanic in Hoover, AL, shares some of the typical symptoms of a bad fuel injector:

Fuel Leak

If you notice fuel leaking from your car, it could be a sign of a bad fuel injector. Fuel injectors are responsible for delivering fuel to the engine; if they leak, it can cause a decrease in performance and fuel economy. In some cases, a fuel injector leak can also lead to engine damage. If you think you have a fuel injector leak, it’s necessary to have it checked out by a mechanic as soon as possible.

Engine Misfires

One of the most common symptoms of a bad fuel injector is engine misfires. If one or more of your vehicle’s cylinders are not firing correctly, it will cause the engine to run rough. You may notice that your engine shakes or vibrates when idling or accelerating.

Poor Fuel Economy

Another symptom of a bad fuel injector is poor fuel economy. If your injectors are not delivering the correct amount of fuel to your engine, it will have to work harder to compensate. This will cause your fuel economy to suffer.

Rough Idle

If your vehicle has a rough idle, it could be due to a bad fuel injector. When an injector is not functioning correctly, it can cause your engine to idle erratically.


Another symptom of a bad fuel injector is stalling. If your engine stalls frequently, it could be due to an injector not delivering the correct amount of fuel.

Check Engine Light

If your vehicle’s Check Engine Light is illuminated, it could be due to a problem with the fuel injectors. If your injectors are not working correctly, it will trigger the Check Engine Light.

If your vehicle is showing any of these symptoms, it’s important to have it inspected by a seasoned mechanic. They can diagnose the issue and then make recommendations for the best course of action.

How to Keep Your Fuel Injector in Good Condition

Fuel injectors are one of the most important components in your vehicle’s engine, and keeping them in good condition is essential to maintaining your car’s performance. You can do several simple things to keep your fuel injectors clean and working correctly.

First, use good quality fuel. Cheap gas can contain impurities that can clog your injectors. Second, have your injectors serviced regularly. A professional can clean and inspect your injectors and ensure they are working properly.

Third, use a fuel additive that contains injector cleaners. These additives can help prevent deposits from forming on your injectors. Finally, be sure to run your engine regularly. This will help keep your injectors from becoming gummed up and clogged.
