Yesterday I was having problems while driving. I turned into an Autozone and their diagnostics said it was Spark Plugs and Ignition Coil. Ok, it was about time to get those changed so I bought both of them and planned to change them out today. Today I popped the hood only to find a birds nest sitting on top of the engine....Its been cold here and I guess I hadnt driven in 3 or 4 days....Anyway, after cleaning up the nest I saw one wired had been badly frayed and another wire had been completely cut in two. After looking around the forum I feel like I know what to do but it also looks like its a completely new Wiring Harness that I need to purchase and put in. That's a little more than I'd like to spend right before the holidays.
Question: Is this repair a fully new Wiring Harness or is there a cheaper route, where the end result will hold up and be just as good as almost-kinda-maybe-new?
