1970Custom
They call me Spuds
List of replacements:
-IPR
-ICP and pigtail
-EBP sensor within last year, little drive time since.
-New alternator and FICM circuit board
-VGT solenoid
Will start and run like it should until throttle is touched then it starts loping if its in gear sometimes stalls.
Manually control duty cycle of IPR and that issue is resolved but still won't boost. Can manually control duty cycle of VGT with similar results as IPR. Letting truck control itself the IPR idle value is 15%. Cranking has the correct values.
ICP plugged in I have half the required psi under load but holds around 600psi at idle up to about 900psi. Disconnect ICP and my desired vs actual psi rise within a couple PSI but truck still won't boost or shift on its own.
I have a hard time thinking its HPOP as it fires easily hot or cold. I guess it still could be though.
Currently has A p0069 and a p0470 and low injection pressure (can't remember code off hand). Baro, EBP and MAP are all relatively close.
