Came home from work today, no traffic on a nice big freshly paved road, so i opened the truck up some. I assume i was running 90ish as my tach was sitting at 2900. Anyways i only ran that speed for maybe a mile, rest of the time i was doing 70ish. While i was cruising at 90 it threw the regular ole ICP code, truck was running at 75% DC. :cursing: Had to back down to 55 as i was getting close to town, and i cleared the code/CEL. The pump doesn't hold pressure worth a damn, so the high DC is nothing new.
Drove normal the next couple miles home but the truck was running really choppy, EOT was around 210 and slowly dropping from my run, but overall nothing out of the ordinary for the truck. Its never ran smooth, and when its warm its always choppy. Pull in the driveway and decided i'd run a CCT just to see if anything was up. Immediately throws P1248, and also shows P1211, but no CEL. At idle DC is normally 10.3% or around there if i'm remembering correctly, it was sitting around 14%. So i cleared the codes, tried CCT again, and this time it ran through it just fine and came back with all systems passed.
ICP sensor is about 2 years old, from Ford. Haven't checked it in a while but last time i did it was still nice and clean with no leaks anywhere. IPR is used, mileage unknown but it and the HPOP came off a bus motor i bought last winter that was told only had like 114k miles. Never touched the IPR as i didn't have a wrench at the time, just pulled the HPOP off the bus engine and threw it in my truck. I've now had them on the truck for about 7k miles.
So, any ideas as to what could have caused it, or is it just a freak issue? My truck will randomly throw codes, but recently its calmed down a lot and hasn't been throwing even normal codes, so this may be nothing. Just never dealt with it before and not sure where to start.

Sounds like you just don't have enough HP oil to fire those stage 2's.
