New guy here, My 02' f250 just turned 300k and on the same day I lost my HPOP, IPR, ICP AND the #2 injector "O" rings. Replaced all of the above and now I have several issues: 1. High idle when at operating temp. and in gear(Auto) only. It starts and runs perfect when cold. 2. Runs rough and misses when at operating temp. 3. Extremely poor performance when it reaches OP temp. 4. What really has me confused is that there are no codes present.
I do not have access to an AE, but that will be changing within the next few months. For now I have all of you fine Americans to lend a hand to help a Texan in a time of need. Thank y'all in advances.

Had the F250 scanned by Diesel Tech, inc. in Leander, TX yesterday....everything looks perfect except the #8 injector is on its way out, plus a slight negative boost pressure. I'm wondering if the Turbo is compensating for the weak injector.

What brand ICP & IPR did you install back in?

the high idle issue when warm and no code can be a ICP

what was the symptom when the HPOP, ICP and IRP when out??? HPOP can go out but not common.

First, never seen a scan tell you your injector is on its way out. Especially #8, it always fails. Boost leak is a good start. To be honest. I won't be giving any more advice on this one until you remove the Edge unit. No not un plugged. Harness right off the engine. 90% of the time I see an issue like this, its the Edge unit. They are prone to failure, mass numbers of them in both generations, and they cause all kinds of crazy engine related problems. My truck is the prime example. It was brought up from texas, totally stock except for an edge programmer. Beautiful truck real low mileage, no issues. Turns out the guy that brought it up here was selling because, yup you guessed it, it would run like crap when warm, and completely shut down for hours stranding him. He thought the truck was toast, and sold it to me real cheap. I removed the Edge that night. I drove that truck no issues for two years before I decided to do a power build. I then swindled Edge into replacing the unit with the new generation. THey did. Two months later. It packed it in and symptoms came back. Still have it sitting in a box if you know anyone who wants that junk. Take it off, drive without it. If its not the issue, we can go from there.

I probably miss something.... did see anything about a edge install??? BUT if you have one, remove it like Absolute said. totally agree with the above. not gonna be the first time a edge cause problem.

on edit: never mind just see it on is second post signature

I always go OEM on everything. The AE was showing normal ICP numbers. I should have gotten a copy...

I will agree with you on the Edge removal, although I replaced the #8 before it totally shut down and what an improvement! Almost like a new truck....except when it reaches operating temperature. I will be taking the Edge programmer out this weekend, given its ten years old, and drive it for a couple of months without it. While I have it out I'll probably replace the remaining injectors with Alliant Injectors. Any suggestions on a replacement programmer? I was thinking more along the lines of a DP tuner. Thanks.

Good choice , but before you do, get some gauges to monitor your trans temp, egt's and boost, etc, maybe a Scangauge11 will be a good choice for you.
The scangauge won't read F/P , but will do so many other sensors on the motor or transmission.
You'll have to fit a remote gauge for F/P .

You were right about the ICP being the cause of the high idle issue. I replaced it and it run like new. Thanks for your help.
