Ok guys Here we go
I have a 1999 Ford F350 Powerstroke with manual trans 4x4

I had a problem with the T.P.S. in the floor conected to the throttle pedal
It would not accelerate I replaced the sensor and it cured part of the problem Now when I put the transder case into 4 high or 4 low I can't accelerate Put it back into 2wd and its fine

Is there another controling sensor Or some other problem

Thanks John

 

BUMP! Anyone got any ideas? Might want to ask in the 7.3 forum too.

 

Wow this is a strange problem. I'll bump it back up to the top in hopes someone has seen this issue before.

 

That is strange, give us a little more info. Do you have ESOF or manual shift lever for the 4x4? Tell more about what you mean "can't accelerate". Engine won't rev up, or truck won't go?

 

I posted in the 7.3 forum, and put a link to this thread in it.

Maybe those guys can help out, this is very strange.

 

Definatly need more info. I'll look into the wiring diagrams tommorow to see if there is any "cross reference" between the TPS and the ESOF.

 

yeah, what he said.
