    hi guys ive got a misfire on tickover the engine management light is also on. Ive had the fault code read and its come up with a multiple misfire. the car does not misfire when im driving its only on tickover so far ive change the coil pack and knock sensor. ive wipped the plugs out and you can tell theyre well used could this be the problem and can a plug bring on the engine management light
