1997 throwing a code, need guidance
my 1997 f350 is thowing p1211 and the truck is running like crap. ive got a driver pulling an empty car trailer back from ohio and he cant build boost over 2000 rpms. when he gets to that point the truck will just fall on its face. Ive had the codes cleared and its been throwing this same code now, and i dont know what i should start doing with it.
P1211-IPR ICP pressure above/below desired Continuous and KOER on-demand test IPR valve failed, stuck, or shorted to ground.
now there IS NOT a chip on this truck, so im guessing the hpop is going out, is there anything that i can do to trouble shoot this so that im not just replacing parts. thanks for any help guys
