I have a 1994 E320 with wiring problems inside the spark plug area. The car runs on 4 cylinders, sometimes 2, and I've narrowed it down to the wiring. If i wiggle or twist the signal wire from the harness on the coil packs, sometimes they start firing off.

I want to know what my options are. Is it feasible or realistic to replace just the wiring that runs to the coil packs on the engine harness, or does the entire harness need to be replaced? If so, where could I buy the wires I need for just what I need? Is it just something I need to cut out of a donor car?

Known problem , the entire harness needs to be replaced. Search "wiring harness" "eco-junk" etc. is kind of pricey $$$$ 1100-1550 depends on type. or you can find a use one built after 1997, .... use the search button.
