Need some advice here. I recently had some cold, long, start issues. Not a FICM problem. It seem to be resolved after adding Rev-x and cleaning the HFCM; however if the truck sits for more than a day it still takes an abnormally long time to start. I need to take a 2K trip tomorrow, and I'm debating on pulling my IPR valve to inspect the screen before I take off.

If I pull the IPR to inspect, do I have to replace any o-rings or seals to put it back?

What are normal IPR values? I'm seeing the following, Idle: 26% Hwy: 40-50% WOT: 60-70%

TIA

the idle is about 3-5% high. Mine idles at 21-23%. May have a bit of a HPO leak. Have you done any updates yet?
