Clean fuel injectors are a must for peak engine performance, fuel economy and emissions.
If the injectors are dirty and can’t deliver their normal dose of fuel, performance, fuel economy and emissions are all going to suffer. Dirty injectors can’t flow as much fuel as clean ones, nor can they delivery the correct spray pattern that is so essential for clean, efficient combustion. The fuel feedback control system will compensate for the leaning effect once it is in closed loop, but it can’t correct the underlying condition that is causing the problem.
The injectors need to be cleaned, if an engine is experiencing any of the classic symptoms of dirty injectors, such as lean misfire, rough idle, hesitation and stumbling on light acceleration, a loss of power, and higher hydrocarbon (HC) and carbon monoxide (CO) emissions.
Lean misfire may also trigger a misfire code and turn on the Check Engine light on 1996 and newer vehicles with OBD II systems. The code often will be a P0300 random misfire code, or you may find one or more misfire codes for individual cylinders, depending on which injectors are most affected
If your automotive service need involves your fuel system our automotive service experts want you to know that the purpose of fuel is to provide the ingredients to the engine of the automotive vehicle. The automotive air-fuel mixture must be in proportion to the speed and load placed on the automotive engine. Major parts of the fuel system include: tank and cap, emission controls, line, pump, filter, carburetor, and intake manifold as well as the gauge, which indicates the amount of fuel in the tank.
