Question about high idle at startup?
I have a prob with high idleat Cold startup. I've been reading about Benzes that idle high at startup and im getting mixed results as to the cause and fix. My car not only does it at sold start but it also does it sometimes when I park and put it in neutral. The rpm will run high then slowly decrease to normal idle. It can't be a old cat causing this if the car is at operating temp. How can I fix this?

How high is the idle? How long does is stay high and does it drop after 30 seconds or so. More color/specificity would help.

For a cold start that looks perfectly normal, If it's doing it when hot and going back to P or N then you may have an issue.
I would be cleaning the throttle body and checking the crankcase breather hoses for leaks. The C32 doesn't have a air mass meter so air leaks dont show up easily but would give you symptoms like that.
