Emissions Issues– When the fuel is not sufficient to enter the combustion chamber, the engine may change the air/fuel ratio in order to improve exhaust emissions.It may appear as if the engine is about to quit functioning. To put it another way, the idle speed will drop dramatically. It’ll seem identical to a faulty spark plug. Idle Issues– A slow-acting fuel injector that isn’t atomizing fuel efficiently will have a hard time idling in your Cherokee.It’s difficult to get going– If some of the cylinders aren’t getting enough gasoline, attempting to start the engine might be difficult.If you do end up needing to replace the injectors, they will set you back only a few dollars each. That’s why, before changing any injectors, it’s critical to check the rail pressure. The symptoms of faulty fuel injectors are very similar to those of a failing fuel pump or fuel filter.
