rough running
Update: I did go dig deeper, which I had hoped to avoid, and replaced all of the injectors, and the entire engine wiring harness. Also, cleaned the MAP sensor, replaced the engine coolant sensor, and cleaned the IAT sensor which was just a glob when I removed it. Previously, I had removed the EGR loop and the EGR, but reinstalled the EGR and plugged it in. Last weekend I drove the truck to Memphis and back, and it performed flawlessly. I think better than it had ever run. During the trip out, I got 13 mpg. Not by the lie-o-meter, but doing the math. That is a benchmark for this truck. It weighs just under 10K, and has 4:10s. The long and the short of it is the re-flash was not causing my rough running cold. Oh yeah, I can actually start and drive the truck before it warms up now. Thanks for a great product, and for getting me off my duff to do what needed to be done. it really is a pain in the *** to work on these things.
