Yes, I've search, and tried everything. No sucess.

(1983 380SEL) will start as normal, but the either stall out or the revving will go up and down (50-2000 rpm) until the car warms up.


Sofar I've:
-Checked and re-soldered the ICU (and cleaned contacts)
-Cleaned the air-slide valve (cleaned with brake cleaner and lubed with atf)
-Replaced thermostat and coolant (had green coolant)
-Changed spark plugs
-Cleaned contacts on the sensors on the thermostat housing


Every contact that was cleaned also got a dose of di-electric greese. cleaner used was caig deoxit. Only thing left if the fuel system (injectors and injector seals) an italian tuneup, maybe?
