I was driving home from dinner the other night when my check engine light came on. The car was running fine and then all of a sudden the engine had a bad skip to it and the light came on. It definatley felt like a misfire, probally was running on 5 cyl. This problem continued on for about 2 miles and they dissapeared and the light went off. The issue has not returned at least not yet. Any ideas on what it may have been? The car has 45k on it and this is the first issue I have had with it. I was thinking maybe throwing a fresh set of plugs in it.....

I have the same problem with my M43 engine. It has 35k kms on the clock.
When was the last time you change the plugs? I changed mine abt a month ago and didn't solve the problem. I'm still trying to find some answers for this. Any takers?

oh btw..mine did not throw any error warning, though.

misfire/CEL

My 2003 325XI did this a few months ago. the shudder, then CEL appeared. I ran the codes and it said a misfire on cylinder #4. and the coolant thermostat was stuck open, making the fuel mix very rich. My Indie put in new plugs and thermostat,s he she runs great now.

Did you run your codes??
