HELP! I have a 1994 S500 w/82K on it. Car runs fine at speed but after getting warmed if you come to a stop it begins to miss and when you start from a stop misses really bad and even stalls out at times, I took to a shop that specializes in Mercedes they replaced cam and crankshaft sensor and also said it needed an ignition control module. After trying 4 different modules I still have the issue and not sure what to do any help would be greatly appreciated. Dist caps and rotors were replaced less than 3k ago so doubt it would be that, Thanks for nay help/suggestions.
