What are Fuel Injectors?

Fuel injectors are essential components of a car’s engine, responsible for delivering fuel into the combustion chamber. They spray a fine mist of fuel, which mixes with air and ignites to power the engine.

One of the first signs of dirty fuel injectors is a noticeable drop in engine performance. The engine may struggle to accelerate or feel sluggish.

Poor Fuel Economy

Dirty fuel injectors can cause your vehicle to consume more fuel than usual. If you notice that you’re filling up your tank more frequently, it might be time to clean your injectors.

Engine Misfires

When fuel injectors are clogged, they can cause the engine to misfire. This means the engine stumbles or hesitates during acceleration.
