The idle on my 1983 500sel is running quite high at approx 1000 rpm. It runs this way and then goes up to 2000 rpm and back down etc... I have tested the wires leading to the idle speed sensor, cold start sensor with no avail. When you turn the ignition on you can hear a switch click. Dos anyone have any words of wisdom to help point me in the right direction??
This car did sit for a while before running again. It was imported from Germany from new. Recently just replaced the ignition control unit. I'm really hoping it's not that, not cheap!! Please reply with any advise.
