I've seen posts on this before... but for the life of me can't find them again. My 05 comp g has an issue after starting it warm. When I start it up first thing in the morning, it's fine. But if i turn it off for a few minutes, up to an hourish, it idles low, misfires, and acceleration is sluggish along with crappy gas mileage. I have heard there is a tsb for this... HEARD there's one, not sure. I just recently got hptuners and am wondering if there is anything i should scan for to help troubleshoot this. I have just recently dialed in my fuel trims hoping it would help... but same issue. Just for regular maintainence I have changed out plugs, cleaned tb and maf, and also replace lim gasket... no change in condition. Mods are s1x, 3.4 pulley, fwi, 180 stat, al 104's, and i'm working on the tune. Any help would be appreciated.
 


Haha oops forgot about those... speed daddy headers with 3inch high flow cat and 3inch catback with borla mufflers. I've been in this game for a while, but turn stupid when I have an issue I can't figure out. And this one has been bugging me for a while now.
