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?

u may have water in your gas or condensation build up

get a bottle of brand DRY GAS and follow the directions...it has happened to me before in other vehicles but not the M3 and Dry Gas got rid of the problem once and for all

select a good gas station to pump into your baby... ...u'd be suprised how many of them get away with cheating you...:ben:
