My 94 E420 has an odd intermittent problem that may also be the actuator. The engine rpm surges occasionally (or maybe the throttle isn't closing quickly enough?), most noticeable upon deceleration and braking, but occasionally at idle. It is VERY disconcerting but brief, to have this surge when I'm trying to stop, or at idle in the garage or a drive through. I noticed this after cleaning the throttle body. I've replaced the rubber sleeve that attaches the mass flow sensor to the throttle body and the car has had both upper and lower wiring harnesses recently replaced. Any thoughts?
