Rough idle fixed
Just want to everyone that the rough idling of my car was due to the deterioting condition of the wiring harness. Tom and Suginami are right. I bought the wiring harness at the MB dealer in Oakland for $565.00. It took me only two hours to install the harness. The car is running smoothly and with more power now. No more oil leak.
Here is the picture of the bad wiring harnes.
