Have a 1994 e320 cabriollet,the check engine light is been on,I understand the wiring harness must be replaced,lately transmission has been giving me problems,it downshifts or gets stock in first or 2nd gear.
Is this due to the wiring harness,I was told there is electronic speed control on these cars,I am wondering if this has anything to do with it,before I spend a lot of money for transmission.
All replies are yrgently needed and appreciated.
