Did that end up being your issue? I've been fighting that for over a year, maybe even 2.....I told the shop I go to to replace it but I'm not 100% confident they did. I have a reputation for being a hypochondriac.Swapped out the IPR this morning. Nothing abnormal seen on the old one, but didn't expect to see anything either. No way to tell if it's the original from when the truck was manufactured, as I bought the vehicle used, but it's never been removed by me the whole 65K miles i've had the truck. Can you tell if it's OEM by the these numbers or is there some identifying marking on it?
It did take some coaxing. I remembered it was tight when I pulled my turbo and tried to remove it then but was unsuccessful, so I told my dad that this might end up being fun. An 18 inch 1/2" ratchet, a 2' cheater bar, and some bloody knuckles later, we convinced it to break free 🤣
@Hydro Send me your address in a PM and I'll send this one to you for FA if you still want to look at it.

Jury's still out at this point. Give it 6 months and I'll report back 😁Did that end up being your issue? I've been fighting that for over a year, maybe even 2.....I told the shop I go to to replace it but I'm not 100% confident they did. I have a reputation for being a hypochondriac.
Not like that, but wow it makes me feel better about my issue. My truck starts great and runs great. It's is only when truck is all warmed up and when I get off a freeway and sit at stop lights. The idle will go from steady, to floating up and down between 590 and about 700rpm while icp voltage and psi fluctuate with it. IPR then sits at 25-26%. Then I go a few blocks and it's back to 22% and idle settles at 635-645. You and Bismic actually tried helping me out when I first posted about it. All this time and I still haven't found it.
I'm not sure if my issue is resolved yet either Last time it went 4 months without acting up. I swapped out the IPR on August 25th, so in 5 more months, i'll let you know
