I have a 1989 W210 190e 2.0 (similar to 2.3 model) in Australia.
Replaced OVP, Idle Control Valve and Fuel Relay Pump.
Engine still cuts off when the tranny down shifted to lower gear and the rpm becomes erratic and decides not to go up again below 500rpm.
Could this be a tranny problem?
I also noticed that my speedometer and trip meter works only when the car is still cold and stop working when the car has warmed up.
This is when the stalling problem starts - when the speedo isn;t working.
Am I looking at a serious prolem here - electrical, tranny, cable?
Please help!
