Message: [QUOTE="Idahopwrstroke, post: 1531472, member: 31505"] After the last ditch of changing tunes the problem still persisted and I got angry and started yarding around on wiring. Got the truck to shudder at idle when moving wiring around the fuel rail pressure sensor. Turns out there was a wire that had internal damage and was slowly failing and as the number of strands decreased over time the problem began to manifest itself. As the wiring warmed up the resistance in the remaining few strands caused incorrect readings from the fuel rail pressure sensor. I ended up having to cut the pigtail out of the harness and rebuild it by taking the connector apart and resoldering the wire to the termination inside the connector and then soldering the three wires back into the harness. An unbelievable amount of frustration for the end fix. Yes, the damage to the wiring was from the wreck that caused the pickup to be totaled at 16k miles but it took that long for the wires to fail inside the insulation. [/QUOTE]
