Truck ran good for 200miles down the interstate. Stopped to drop off my load and let it idle for about a half hour and it started missing like a harness went bad. Tried the usual, unplug one harness and truck shuts off, unplug the other and only a slight change in the sound. I changed the harness and it made only a slight improvement and it still runs like its not firing on that side. Ohm'd wires from idm plug and they all fall within spec of 2.8+. Took off valve cover and pulled each plug from the injectors while running. Cyl 1,3,5 cause no change in running, cyl 7 makes it run worse. So it seems like 1,3,5 are dead in the water.
I think this points to idm or could three injectors go bad all of the sudden like that? Ill buzz test them when my brother gets here with my scan tool.
