rpm surges on idling- 300E 1993- 104 engine
 
My brother in law has a 1993 300E with 3.2 liter engine...

When the engine gets hot the idling surges...

He replaced the airmass sensor and the cruise control actuator already... but the problem remains...

Please help...

This could be a wire interruption in the Mass air flow circuit. It is time to get out the ETM and the Meter.
