Any ideas?
I do all the work on it my self, other than alignment adjustments.
The issue is, I do know ICP needs to be changed possibly I got check engine light for it and though sometimes it clears up, the truck will spit and sputter and run rough sometimes cold or even at operating temp. Im changing glow plugs soon as well. I didn't know if any other issues could cause the rough idling/power loss other than injectors?
It doesn't do it all the time and if I rev to 3k rpms it'll clear up? Any suggestions other than changing ICP? HPOP runs normal, and IPR.
Then scan for codes and post the code numbers of what you find.
You also need to post what year engine you have when you start a thread - there are some differences in year models.
If you are set on changing the ICP sensor, then also plan on changing the pigtail (connector w/ wiring) also.
