1984 Mercedes 500 sel. I have an extremely high idle, at 2100 RPM. I went to a local Mercedes mechanic, and he let me take a used idle computer and put it in my car to see if it was the problem. That didn't do anything to fix it. I have cleaned the idle control valve, still no fix. When the connector is pulled off of the valve, nothing happens, no change at all. I'm running out of ideas. Anyone?
