190E 2.6 dies when rolling on idle??
 

I have the problem that my 2.6 dies when i rolling with the it on idle, doesn't matter if I'm rolling forward or backward with that bloody bastard.... this happens if i have no gear no clutch, clutch no gear, gear and clutch

I've checked the TPS, The EHA, the idling switch and so on, ground connections is also checked...

the lambda sond gives an constant voltage@~400milliVolts.. is the CO-settings out of range or are the sond broken? I know that the sond shall give a fluctuating voltage between 0.1 and 0.9 volts

the exhaust has lo leaks

heeelp!! Im getting mad :mad: the lambda sond has been changed today, still same problem....

I would clean the Idle Air Control Valve and test the switch on the end of the throttle linkage. Also clean the AFM plate as well. Check for vacuum leaks as well.

I have checked everything like that. The problem is not there

can it be the generator?

OVP(overvoltage protection relay) provides power to the idle control circuit. Something else to consider.

the ovp has been changed for about 2 months ago, sometimes the engine (when idle) rush up to 1.5-2kRPM for some seconds and back to normal idle again
