Ok, i can be driving down the road anywhere between 25 and however fast, all of a sudden my pedal will just go away and the truck will start slowing down. I can put the pedal all the way to the floor and let up, then roll into it again and it will come back. I thought it was a fuel delivery issue so i put a new lift pump on it, still doing it ! Any ides ? Starts hard sometimes too. Throttle postion sensor ??

 

prolly yer APPS

need to do a re-set on it

turn key on but dont start
slowly press throttle to floor
slowly let throttle up all the way
turn key off
start truck and enjoy

I rescued my son in laws truck after he paid 160 bucks to have it towed............32 seconds later I had him going and didnt lift the hood.......heheheheeeee priceless

 

If the simple reset doesn't fix it use this link for directions on how to check your APPS and do the full blown reset. https://www.dieselbombers.com/24-val...tomy-apps.html

 

Any smoke?

Resetting the APPS is not a long term fix. Got any codes? My guess is the VP is going out slowly...

 

Sometimes if you dissconnect the battery the sensor just loses it's setting for some reason and once it's reset it works just fine again. I always do the reset after everytime I dissconnect everything just to say I did it.

In the case of resetting the adjustment of it I think over time they just work themselves out of adjustment and need to be put back in place. I may wrong here cause I really don't know what happens to them but I re-adjusted mine about a year ago not long after a new VP was put in and so far it works great. Lowered EGT's and picked up a little power. Most importantly it stopped the dead pedal issue I was havin.

 

Not saying you aren't correct. My example there is for my truck with big injectors. I reset the APPS because of the loopy idle and within a week it is back. This is likely an issue with the injectors themselves or with the shuttle inside the VP.

 

Ok guys i did the reset on my APPS...Better but still doing it a bit. Is it safe to say it pretty much shot ? Or should i try re-calibrateing it before i buy a new one ?? Thanks for all the help !!!

 

well it sounds like you need go go indepth with this thing................a new one is 430 bucks so thry this first
