i dun know about the clutch but, the idle issue unless you have the tools its a lot of guess and check. the earlier 190e's had an adjustable iacv, adjust that and see how it does, make sure u mark the orig position. if not adjust the amm (using a hex key) turn the screw in the hole on the center of the air cleaner. whats the position of your distributor? you can retard and advance ur timing there. the screw should be about center. i say that you take apart your intake manifold and reseal the bottom of the air flow meter, the throttle, and the intake itself. this is a good time to clean the intake too.
