(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.

The shake upon idle is not constant. It usually happens when either going from high speed to a stop or at a sudden stop.

It sounds like it needs park plugs have you changed them?
Brand new plugs were in it. Ac delco iridium's. Spendy, changed the coil pack with 3 different ones then changed the fuel injectors, runs fine now, thank you for the idea though
