truck actin up...TPS sensor?

[strokin6L]

Damn, truck started acting up alot today. Put it in drive and start to accelerate...then all of a sudden it'd go flat on it's face and i'd lose all peddle. Then after a little bit it'd come back. When it does the glow plug light would flicker like once or twice then go out every time this happened. I also noticed that on my edge insight the throttle postition setting would stay on the certain % when this would happen. It just so happened that the last time it did this the pedal postition was at 25% and stayed there even in park idling. Makes me think the TPS sensor is taking a dump. Anyone got any thoughts?

ive been chasing tps problems for a while and it sounds like youre on the right track. Are you getting any codes?

Well it's not the APP(accelerator pedal position) sensor. Swapped the one out of my cousins truck and it didn't change anything. However my truck started stalling now also. But i found out that once it got up to temp it stopped doing it...so i'm at a loss right now. i'm not sure i actually feel safe driving it because it actually stalled on me while driving. It did throw a code...P2614 camshaft position signal output circuit low. But the truck will automaticlly throw that code when it stalls so i'm not 100% sure that it can be the camshaft sensor.

03-04's are probably different, but my pedal throws TPS codes. Do you still have the butterfly in your truck? I know early trucks have a sensor there, the failing sensor may be closing the valve and cutting off the air supply to the engine causing it to stall.

no valve. My truck had the assembly but never had the actual butterfly from the factory. And actually there was never a sensor in the throttle body assembly that the connectory plugged into.

I haven't been running the stock elbow for over 6 years. Was running the CFM+ large mouth for a long time and now i've got the No Limit cold side CAC pipe.
