Dirty or clogged fuel injectors can have a serious effect on your car’s overall performance and can lead to untimely car break downs and significantly expensive car engine repairs.


Below are some of the key symptoms of dirty or clogged fuel injectors and can be fixed using ProFlow’s advanced Ultrasonic Fuel Injector Cleaning Services.

Rough Engine Idle

One of the most common symptoms of dirty fuel injectors is a rough, choppy, or violent engine while you are sitting at idle. A fuel injector’s job is to deliver fuel directly into the engine cylinder through the fuel rail before it is burned during combustion. If this process is not done properly or efficiently due to dirty or clogged fuel injectors, a rough idle will occur.


Poor Fuel Economy

Another common symptom of dirty or clogged fuel injectors is poor fuel economy. A clogged injector will starve that cylinder of the proper fuel, which in turn will cause your engine to not run smoothly an decrease fuel economy. A faulty fuel injector also may inject too much gasoline into the engine, which is wasteful, less efficient and will lower your car’s fuel economy.


Surging Engine

If you feel your engine surging, your car may be suffering from clogged or dirty fuel injectors. This can cause the engine to surge too fast and then accelerate too slowly. To the driver, this condition will feel like an up and down motion.


Misfiring Engine

Another symptom of dirty fuel injectors is a misfiring engine. This will occur if your fuel injector is not sending in enough gasoline into the engine. This symptom may also be caused by clogged fuel injectors. To the driver, the misfiring engine will feel like a delayed acceleration when you touch the accelerator.
