1992 S500 140, 119 engine
Recently it develop a rough ideal and loss of power. However after driving for 5 minutes, it went back to normal. Last weekend the car just die while driving. Pull to road side. Wait for 5 minutes. It won't start (just crank). Wait for 2 hours, it start but it ideal really rough. Very poor respond from throttle. It also give out black smoke. Take off the negative terminal, wait for 5 minutes, connect it again and re-start. No problem in starting, but very rough ideal, very poor throttle respond. It is not drivable anymore. Search the forum, it is most likely MAF. Open and take of MAF and at the same time the throttle actuator was also out of the car.
Open up the throttle actuator and find the wiring harness is gone (engine wiring harness was replaced 3 months ago). I am thinking of re-wiring the throttle actuator wire however need wiring diagram. I have taken pictures of both parts.
Appreciate someone to provide wiring diagram from one end of the throttle actuator to the other end.
Thanks.
