I'll poke around for it in Friday (next day off) and see if I can locate/clean it. I've already done the braided stainless ground that runs from the driver's side cylinder head to the firewall. Is this other one on the passenger side, kinda behind the fuel pressure regulator? Don't recall seeing another one there when I had everything pulled off to do the injectors last time, but I wasn't really dealing with ground wires back then, either... SUSPECT UPDATE: - Coolant Temp Sensor? - MAF? - TPS? - Overlooked ground wire(s)?
