M3 Engine Misfire

1474 Views 7 Replies 6 Participants Last post by  NAZology
Anyone with an e46 M3 ever notice a slight misfire or hesitation of the engine. I have an 03 with only 1,100 miles, purchased on 12/31/02. Occasionaly, I will feel a slight hesitation, or misfire. It usually happens under very light throttle conditions around 2,000-2,500 rpms. It is only a single occurance and then everything is OK. I have never noticed it under heavier acceleration and have not done any WOT since I am still in break-in period. Check Engine or EML lights have NOT come on.

It only occurs rarely, maybe once every 30-40 miles, but is definitely there. Any ideas what might be causing this?
