Dirty injectors can cause excess wear and tear on your fuel system and engine, which can result in costly repairs.īefore it gets to that stage, a quality fuel injector cleaner can help by dissolving gunk and cleaning fuel lines and injector nozzles-all for just a few bucks a bottle (prices vary and some are very inexpensive).

If the ECU isn’t getting the proper voltage response from the throttle body, it can’t be sure of how much it’ll really accelerate your Malibu from the gas pedal input.Īt this point, it turns on the reduced engine power mode in order to keep the vehicle from running away from you.
