My 1988 750il occasionally starts on only 6-cylinders. The condition occurs primarily on a warm restart (after the car has been sitting for 10-min to 1-hour). It runs on 6 for 2-4 minutes at which time the remaining 6 cylinders come online and all is normal. I have not had a chance to diagnose which bank is at fault, nor whether it is an ignition (my guess) or fuel related problem. The problem never occurs on a cold start. Has anyone on the list experianced similar problems? Anyone wish to offer an opinion regarding the cause?
