idle speed high?
I have a 89 300E newly acquired. When it is in drive, the car creeps forward as soon as the brakes are released. When releasing the gas pedal on the road, the idle speed appears to be pulling the car slightly. Looking at the tach, at idle, the car is close to 900rpm in gear. If in N, the idle jumps to 1000-1050rpm.
Is there a simple adjustment to bring the idle down slightly? I am not familiar with the injection system, but it feels like a old carburated car .
