I'll be goin down the road at pretty good clip, but if Im on a slight hill or give just a little more fuel.... the enigine will bog down on me untill I let of the pedal, and slow down then it kicks back in to gear... does ANYBODY have ANY idea why this happens.. is something wrong with my turbo?

 

You need to fill out your signature on what truck you have and what's done to it.

 

here are some things I would check out,
1) Dirty fuel filter
2) Leak in the intercooler or the rubber hoses, they can become cracked.
3) I dont know, but try to clean the air filter or replace it.
Hope it helps!

Wheelo

 

thanx thought it was filled out.?
92 dually

 

info......

 

I just saw a posting about this same problem a few days ago. Check your TPS ( throttle position sensor). Do a search on here... lots of info
