A few times this past month, my truck would idle randomly up to 1700 then down slowly to 1200 and eventually it would come back to normal. some times it would be irratic. it has happened the most while in park. today, i parked my truck and left it running as i went inside the house. i heard it rev up while i was inside the house. dont believe in ghosts and no one was messing with me :thud:

i have had p0121 (apps voltage) problems with spotty throttle for a while now. could this problem be related to the apps or something else??
