The solution for me was replacing one ignition control module (ICM). I spent a lot of money at a worthless mechanic. Then, I almost bought all new coil packs and spark plugs. I decided to try the ICM first. PTL I purchased the ICM at ecstuning.com/

The problems were not only did I have misfires at idle but when cruising on the highway I was getting a strange vibration/shudder in the car that comes on at about 2000rpms and then is gone by 2200 or so.
