Well, I thought it would be a few minutes.... seems a lot of things with MB takes more than a few minutes.... How does one remove the Cap and Rotor on an 89 300E? There appears to be not enough clearance between the Cap and the engine cooling fan to simply pull it off. Cap/Rotor on my car have been on for 230k km and probably at least needs to be looked at. Seems this is one possibility for my slightly rough idle? Any pointers much appreciated.

- cheers
