2010 silverado 1500 stabilitrak problem

[nick gorske]

Silverado 1500, I did some maintenance work, tune up, tranny cooler lines and I was having a problem with a wicked idle and it didnt wanna run right after. I did some searching and changed the tps. After that didn't fix it I realized I screwed up and put the cold air intake on wrong. So whatever i had a new tps no big deal, the old one looked worn anyway. The other day i was slowing down and warning buzzers start going off and the stabilitrak and traction control lights light up on the dash. No check engine light just those. They only come on and i only have a issue at low rpms and speed. Once i get up and going the truck pauses then goes like it should. I've cleaned the throttle body when i changed the tps, and the maf sensor was cleaned. I swapped the original tps back and it made no difference. Any ideas. I'm freaking stumped. Could it have been the original 1 was going bad and i just happened to of gotten a bad 1 from napa? I've never had luck with sensors from napa but they were the only ones that had 1 on hand.
