can anyone tell me the symptoms of each and how to trouble shoot? I have the location of the IPR and will be cleaning it tomorrow and is there anyway to tell if the ICP is bad. BTW, my truck sputters about 3 miles after driving it and eventually stalls. might start up and run like crap. barely make it home stalling in the driveway.

hey when i replaced the icp sensor due to a code sayin it was bad i still experienced rough idle symptoms and when i unplug the icp sensor while its still running it will idle fine??
what could this indicate as being bad ?
there was also one more sensor down in the front of the hpop infront of the cooling fan that when itook it out it was filled with sludge dirt like stuff i cleaned it out but there was soo much of it? what do you think this could mean?

so is there a way to clean it or replace it and the tube the sensor seems like it went in the front of the hpop i looked at this a few weeks ago...
we just replaced a valve cover harness the other night the cleared up the power issues (one of the plugs was undone) but it still has the rough idle... so even though i unplug the icp sensor you still think that the back pressure sensor is plugged?

yeah i just found it sounds like it could be an issue bec we replaced the icp on the driver side head bec it said it was bad if u unplug the icp it idles smooth how ever we did remove the ebp and looked at it it was completly clogged i just called my freind and i am gunna have him unplug it and let me know if it runs good again it sounds like it could be based on the symptoms i am seeing?
anything else u think might be wrong
thank you very much

I'm having the same problem. Once the engine warms up I have a rough idle but it smooths out when I disconnect the ICP. I hooked up my programmer and it showed the injector pressure was low at idle once the truck had warmed up. I'm going to replace the IPR this weekend to see if that fixes the problem. If that doesn't work I may try replacing the injector o-rings. Somethings causing the idle pressure to be low - I figure it's either a sticking IPR or o-rings leaking.
My truck has the same symtoms, idles rough and when unplugging the ICP it smoothes out. I'm waiting on my ICP from ebay but sounds like this may not be the fix. How much $$ is the IPR and where is the best place to purchase?
