Idle issue after ipr replacement
07 f250 stalled one day and wouldn't start again. With a lot of help from this site, I found the culprit to be a faulty ipr valve. The new ipr got the truck to start again but now has an idle issue.
Truck has a normal idle for the first 15-20 seconds upon starting. It then surges to about 1000 rpm and idles rough at that level. Hot or cold... The rpms stay higher throughout the drive.
I can start the truck and take off before the surge begins and the truck drives great. I can make brief stops and the rpms go to a normal range then, accelerate with no problem. The first time I stop for that 15-20 seconds, it surges again and keeps the high rpms.
My issue seems very specific but I can't find any solutions I feel great about.
No scan tool at the moment. Thanks in advance for any knowledge you guys have on this.
