S500, great car BUT need great help....
Car model, S500, 1992 W140 119 engine
The car was in Limp Home Mode. After reading pcmaker web site, found out the insulation of wiring harness to the throttle actuator and to the injector were gone. Replace wiring harness to the injector and re-wiring the throttle wiring harness. Put all back together the car run realy smooth. After using it for a month or so... the engine start real rough and into LHM. The RPM jumping up and down. Also black smoke coming out from the exhaust. Spray the Air Mass Sensor... no difference.
Thinking of checking the vacuum line, but don't know where to start and how many are there. I have subscribe to ALL DATA through pcmaker web-site and this should help to locate where the components are if needed.
Appreciate the forum help as the car was not running for two weeks now trying to figure out as well as reading a number of thread from this forum.
