Installed a new APPS this weekend. Truck threw low voltage apps code (0122) on a test drive afterwards with the CEL on. So I reset it again, had the codes erased it ran great for two days. Then randomly after a stop light it had throttle for about 2 seconds, then went back to idle for about 5 seconds, then kicked in again and threw the same code. Had it erased again and has run fine since.

Any thoughts on this? Mabye just a glitch in the ecm from the codes?

 

my is doing about the same thing. I've tracked it to the ecm have one on order from a salvge yard. should be here in 2 days. they sent me the pcu first. (some times their not too smart). I took the apps off my dad's and that didn't help put his ecm on that then it would take thottle. would'nt run right because his is a SO and mine is a HO . I hope this fixes it
