Hi, my E46 330Ci has had a misfire at idle since I brought it nearly 2 months ago which iv have had help with on the forum but the other day i went to mc donalds drive through and the misfire got really bad like it was running on like 3 cylinders! Normally the misfire is only at idle but this was also when driving!
After, I pulled up and the car was running terible so I turned it off and turned it back on and then it was fine!?
This has now happened 3 times now in the past 2 months and I know it sounds crazy but its always then driving through mc donalds drive through! although this is probably the only place the car is driven too, then stood awhile, then driven again without the engine being turned off.
Any idea anyone?
