I have 98.5 2500 2wd When i take of sometimes the truck acts like you turn the key on and off. Some times it is relly bad like take the fuel away for a secound or two. It doesnt do it all the time. The check engine light comes on when it does it bad and then goes back off after a little while. The code i got said APPS voltage low. I recalibrated the APPS and it still does it but not bad enough yet to turn the check engine light back on.

 

any ideas?
