Hi Kent, Brook here...(of the Larry Mans clan)... 1982 Turbo W123 My car (Sherman) is idling way too fast these days. I took it into my MB shop at closing time the other day, so they didn't have much time to diagnose but we did notice that the "arms" that one pulls on from the engine to "rev" the engine (say, during a diesel purge) are sticking somewhat and not allowing the engine to relax into a normal idle. My mechanic sprayed some lubricant on the arm "joints" hoping that would release them a bit and yet after a few days, it's still happening. A) Have you seen this before B) What's next? Many Thanks, Brook San Diego
