The truck starts up good then it starts to have what sounds like a miss and idles real rough and runs rough under 2k rpm (cold or hot). Any time I let off to shift it runs rough. Have had a Po122 that came and then went off the next morning. Fuel pressure stays around 16-17.
Any help would be greatly appreciated.
