Possible RPM issue...
'95 C36
84,000 miles
Problem: I rev the engine pass 1000 rpm, let off the gas, the rpm drops to about 900 rpm and then JUMPS UP slightly to about 1100 rpm, and then settles at about 900 rpm again and remains there.
*only does this when the car is in "Parked" gear,
*doesn't matter if the engine is warm or cold,
Am I paranoid??

What should I check?
Thanks!
