Engine/Transmission (1998.5 - 2002) How to tell if my APPS is going bad?

[BHowayeck]

My truck developed a slight stutter, threw no codes. Just curious as to symptoms of a failing APPS. Thanks.

When mine started acting up, I depressed the accelerator and the truck stumbled and went nowhere. It idled fine but nothing else. Gary started a great thread entitled "Anatomy of an APPS"... very good read. If it is your APPS, you might want to try adjusting it first... worked for me. There are instructions on the board on how to do it.



Good luck.

Bhowayeck,

Have you reset the APPS by turning the key on (engine off) and push down and then release the pedal slowly, then run the engine?

Godspeed,
Trent
