M3 Engine Misfire

1472 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?

what I would do

If you tend to fill up at the same station.

Try another station and see if that helps?

Im sure its nothing and will be fine once your able to "smash on it" and let that baby rev out!
