(Ecotec 2.2) When my car is idling it has a pretty good shake and the rpm's bounce between 500-1000 and now every now and then the vehicle says misfire detected on a scan tool, but will run perfectly fine when the code is cleared. any clue what may be wrong or what could be done to correct it? I have changed the coil pack/plug wires. I am going to try changing furl injectors.
