Do I need to start a new thread for my continuing problem?
I'm at my end with this problem. I thought it was a spark plug issue, but it seems not. My question now is this. If the ICM is bad, will it cause misfire, or is it possible I just may have a bad plug? I did a cold run on the car just to time and see when the problem actually happens. It seems that at first crank, all is good. Then every 30 sec or so, the misfire starts, then the engine revs up then comes back down. When I loaded the engine (a/c and lights, trans in rev) the engine settles and the misfire is not as pronounced. Then returning the engine to a no load, it is fine. The misfire is so intermittent, that on occasion the CEL flashes when depressing the accellerator, and a lack of power from the engine is observed. After about 2 min the problem is almost gone, but when in park, or sitting at a traffic light, the misfire continues. IF there are codes will the problem persist, or will clearing the codes cause the computer to relearn the engine parameters?
