My E200 has been Mia behaving and mechanics have said it's the harness wire, it's the throttle actuator, it's the ECU. The vehicle just refuses to start sometimes no matter what you do. After u must have forgotten it, you may come back and try to start and it will start. It idle is very irregular and it's fuel consumption is so high. It also doesn't have power but when I throttle down and hold it for a while, it develops power only to loose it and start sputtering at about 4000rpm. Pls can somebody help me out. I will also want to know the particular year it was built as my mechanic says he doesn't have the 16 pin connector to diagnose the vehicle. Pls how can I reset the ECU and get everything back to normal?
