Hi,
Im having problems with my 420se 1990.
I have replaced the following
Rotor arm
Distributor cap
Spark plugs
Ignition leads
I have cleaned the idle control valve and when disconnected the idle rises.
The car starts fine and when warm idles at 1100 rpm unless in drive.
I cant find any air leaks.
Any advice would be very much appreciated.
Values for the sensors would be helpful and a diagram for the vacuum pipes.
