Well, I looked over all the wiring and everything checked out. I even wire-tied some harness sections that seemed too close to the egr tube. Ended up being a damn plastic bag that melted onto my exhaust. lol. Go figure. It's near the rear wheel, so I'm not too worried about it, but I've been trying to burn it off by driving a bit harder, since I can't seem to scrape it off. On the bright side, I did manage to find that my oil pressure sensor was on its way out. Oil all over the back of the block, firewall, and cross member, but nowhere above the sensor. Looked like it started leaking and it was about to pop. THAT would have been a mess.
