07 6.0 Rough Idle?
Hey guys, I am curious... what could cause a rough or choppy idle? I have a 2007 vortec max silverado and out of nowhere the other day I was noticing that it is now surging a little bit at idle... sometimes it will idle completely smooth but then other times it kind of jumps a little bit when it is idling... what could it be? I ran some gum out through the fuel tank.. but it hasnt done anything. And the weird thing is that the truck runs completely normal when you are driving... The truck is basically stock other than the stuff in my siggy. Any ideas or suggestions?

i think i might have just fixed it... i didnt drive the truck around and get it hot though... so im not sure yet... What i did was take the whole volant apart and clean the maf with maf cleaner spray and then cleaned the throttle body blade and wiped around the neck of the intake tube and then sprayed some "deep creep" up inside the manifold all around and let that sit for about 15 - 20 mins... I then started it and let it idle for a couple minutes and revved it up to about 2,000 a couple times and then let it idle back down and ran the a/c too and I couldnt get it to idle rough anymore. so hopefully it is gone. I will keep yall posted. thanks
