IPR Issues ???

Upon slowing down / deceleration truck engine stalls and surges with rpms kinda like have a mind of their own untill back on throttle then it hesitates at first before clearing up ...as soon as throttle is backed of again it does the same crap again ....you can tell injectors are misfiring when it drops down at its idle sequence while coasting down highway under NO Throttle

on a friends truck we just did EGR Delete & New oil cooler ...he did some kind of screen kit in the IPR while it was apart...think we should have just left it alone ??

I think it got crud down in the high pressure oil reservoir that has now made it's way to the IPR. Pull the IPR and check the screen. I'd put money on it that the screen is going to have a bunch of crud in it. Since it's still running you can try and replace the screen again. If you keep running it like this it's only a matter of time before the crud pushes thru the screen and gets in the IPR, then you will have to replace it.

Take it out anyway and inspect it. The junk might just be moving to a different part of the screen after you shut it off. It will just move back into a spot that will make it run like crap later.

He's looking at buying another IPR and just replacing it....I showed him the other thread where you commented on the IPR Trouble...convinced him it was cheap insurance just to replace it and be done with it
