04SilveradoSSway2Low Posted January 25, 2012 Report Share Posted January 25, 2012 i just bought an 2004 silverado ss,it came with a bully dog programmer already installed, the guy recommended that i updated the programmer, so i did, and i put it back in, and now i have a rough idle, its idleing as if its starving for fuel, it will run for a lil bit and then it will stall, while going at slow speeds it stalls, and just idling in park it stalls, please help me ! im so clueless ! i tried pulling the tune and putting it back to stock specs and yet it is still doing it Quote Link to comment Share on other sites More sharing options...
2001silverado364 Posted January 25, 2012 Report Share Posted January 25, 2012 Really doubt it's in the tune. Sounds more like a dirty throttle body/maf or vacuum leak. Quote Link to comment Share on other sites More sharing options...

317tonySS Posted February 9, 2012 Report Share Posted February 9, 2012 I just had a diablo tuner installed in mine today but I was disappointed with the results I'm returning it tomorrow because it is also shutting off when I come to a stop, hopefully it's fixable lol Quote Link to comment Share on other sites More sharing options...
