Question My F 250 stalled

[Bigdog]

throttle position sensor is the potentiometer(variable resister) that is on the throttle peddle. the resisitance changes when you push the peddle to give you your throttle. as far as what pins to check and what the resistance should be, im not sure. i hope some one else can chime in

Thanks Mate , it was covered in dust and gave it a clean , the peddle feels good now but it still stalling when it wants too, again thanks

I'm still think'n Fuel Pressure.

Maybe check the O rings in the FPR ?

My 7.3 did what you describe.. Good static fuel pressure.. but under throttle demands.. it would stumble or die.. R&R'd the FPR O rings (a kit from Ford) fixed it..



(the black one on the sleeve had loose piece that would roll during movement)

G'day Big Joe and thanks for your input as well , I have a fuel pressure gauge on my Regulated Return Fuel System was running about 72psi have drop it back to 65 psi with no change i all so run a FASS as well , i did think it was fuel or air in fuel or air in HPOP, Because it is at it worst when standing still at the bottom of a small or large hill , and when you take off it stalls almost . I am thinking that my not so old IPR is on its way out. Again thanks

G'day again i just did a scan and have come up with P0269 and P0284 could this be the problem ??????

let me see if I can log onto the shops Identifix account from here, and I'll put up a wiring diagram..
might not be a bad idea to give me the VIN # in the windshield..

P0269 & P0284 are both injector codes.. contribution faults, to be exact.. I doubt it's *THE* problem, although it points to potentially *A* problem..
