So, my 02 wagon started running really roughly and blinking CEL light so I took it into the mech and he changed the spark plugs but it was still running as bad as ever. So, he tells me one of the coil wires was busted and the wires are all part of a single wiring harness ($750). His recommendation was to find an existing car in a yard and cut off the wire and solder it to the existing harness.
What do you guys think? Any other ideas?
