Long story short, Issue with truck. Found no spark issue on cylinders 2 & 3 on exhaust side coil pack. Swapped with another, same issue. Figured it was the ICM. I was in the process of taking off the wiring connectors to the ICM. Top and bottom came off fine, but when I removed the bottom, I found a loose wire going to nothing. It wasn't on the connector, but went to the same harness. It was a single black wire, going to a connector, with a single wire coming out the other side, but looks like it pulled out/broke off somewhere. I cant find where it went to. The wire coming out is a clear plastic, with some kind of material sheath underneath covering the copper wires. I thought maybe the Camshaft Position Sensor, but that has all 3 wires going to it. Anyone know? Any help is appreciated.
