Hope someone out help can help me. I have an 88 300e that has a very rough idle. I was told that the car needs a fuel distributor. Injector Number 6 leading to the distributor seems to be bad. Moved the line to another place on same miss. Can a fuel distributor be cleaned to help this problem? Also can the ovp be contributing to the idle. In the mornings I found that the car backfires at the throttle plate and stumbles on take off. The car has new plugs and wires fuel filter. I'm scratching my head on this. PLEASE Help me figure this out
