ICP is the sensor the PCM uses to monitor the high side oil pressure. IPR is the valve the PCM uses to adjust the pressure in the high side oil system. Keep in mind also, the ScanGauge doesn't "read" the sensors and stuff, it asks the PCM for the value and it displays the PCM's response. If you look at the first list of codes I posted, the values and sometimes a short explanation is listed with each one. There is also more info on the PDF file I posted the link to (Hope that link worked for you by the way).
For example:
The ICP should read 0psi with the key on engine off (KO)
It should read 625.5 at low idle (LI)
It should read 1400 to 1450 at high idle (2500rpm) (HI)
And it has an operating range of 0 to 4045psi (OR)
On this list all the gauges have the values, I think Benny (Blade35) fixed that list up for us if I remember correctly.
Happy monitoring!

your guys info is great and very helpful.
so my ficm is fine, hpo is fine. so i guess the only thing else that could cause my little stumble would be a sticky injector. i was thinking maybe doing glow plugs before and see if that would help but i got to thinking about it and if it were a bad glow plug then i would see some smoke with the stumble but im not so that tells me there is no unburnt fuel....right? so i guess now how would i track down which one is sticky. i will more than likely get some revx that i have read so much about and give it a shot. but would like to know how to track down a single injector.
also i didnt say before but im not getting any cel or service lights and no pending codes either. the stuble is only until the engine gets warmed up and you can only feel it when rpms are close to and above 2k.
