Years I’ve been here drinking deep from the well of knowledge and experience, and I don’t know how the heck I failed to learn about this common issue, but after an unfortunate PITA experience that I realize now could have been easily avoided, I’m on a crusade to encourage my fellow eightians to INSULATE YOUR ENGINE WIRING HARNESS BY THE EGR if you haven’t done so already.
My 95 has 220k hard, but amazingly problem free miles. About two weeks ago on a long trip in middle of nowhere Southern Utah, loaded down gear and supplies, I started getting a solid misfire engine hot, under load.
I was able to quickly determine the miss was at #5 cyl. And after a long night of trailside diagnoses that included going over the ignition system, swapping components around, and even swapping injectors around (not fun), I was stumped, and leaning toward a valve seating or head gasket issue. I cut the trip short and limped home.
Once in the shop and I was able to check compression/leak down and found #5 stayed healthy and consistent along with all the other cylinders. Perplexed I thought I’d check 80 tech and quickly came across a thread that told the tale of a #5 cylinder misfire being caused by a damaged wiring harness. I cut back the 25-year-old baked insulation and...
