My FJ has been sitting for awhile, has always run flawlessly with 60k. This morning I started it up and idle was rough, check engine light came on. I read the codes and cylinder 5 was misfiring.

So I went to check the wiring and found seeds and rat poo all over, the little B*&* chewed through my injector wires, right at the plug.

These wires go right into the harness and are really short so I am wondering how to repair/ replace them. Any help would be appreciated.

Never mind, I found a replacement plug with wires, I'll splice them into the wire harness with solder and shrink wrap. easy fix but these rodents are really annoying.

I feel your pain. Had the same thing happen. Cost me over $500 to get fixed. I bought an ultrasonic rodent repeller to place under the hood. Seems to work as I haven't had a repeat.

I hope it is that easy.

I had the same problem. It turned out the pack rat also ate the wiring UNDER the intake manifold. Repair was $5500. We are grateful our insurance covered it - only out the $500 deductible.

Newer cars are generally made with more “environmentally friendly” wire insulation(soy based plastic insulation). The PVC stuff back in the eighties was apparently terrible for the environment but at least it doesn’t smell like food to the wildlife. This is actually why I typically wire my builds/mods with wire from aircraft suppliers, b/c the aircraft industry essentially appreciates longevity over all else. The wire I get is tough as nails, abrasion resistant, chemical resistant, heat resistant, and apparently mice just plain won’t eat it. Sorry it’s not a good solution for FJ factory wiring shortfalls though.

When I stored my FJ60, they got me too. Then an old coonass from Jennings LA told me to sprinkle a seasoning called Tony Chachere's Cajun Seasoning on it. SOB but it worked!! I covered the under hood area with it and no rats, even though there was a rice operation a few hundred feet away.

When you sprinkle it, and get a whiff - you will understand...LOL

I second the Peppermint Oil. I spray it on anything that sits a while (lawn mowers, tractor, etc.) I even spray some inside my tool box out in my shed. Don"t know or care why, but mice hate it.

Did you get it fixed and what method did you use to solder wires? Or crimp? I have the same problem!

Make sure to file a complaint this is no joke and a big safety hazard due to manufactures jumping onto the environmentally friendly bandwagon and costing vehicle owners thousands in repairs.

https://www-odi.nhtsa.dot.gov/VehicleComplaint/

Plastics in wiring in cars now contain such inciting substances for varmits such as:
  • Soy
  • Rice Husks
  • Wood
  • Sugars
  • Sweet smelling substances like Vanilla
  • Peanut Oil
  • Straw
Before everything was 100% petro and not as alluring to critters.
