please help, rough running 94 trans am hi all, reference stats in below sig... my trans am is acting like it wants to die if i drive it somewhere(gas station) run inside get smokes, come out and fire it up, it will run really rough and sound like it wants to die for about 2 solid mins and then it'll be completely fine and run strong. i thought it was my dirty filter choking it on the CAI but i cleaned it and it's still doing it. any advice would be greatly appreciated. the current plugs were changed 1.2 yrs ago, i need to get to that, probably going to change oil within next 2 days, please state if you'd need any more info for solid advice (sorry for the poor grammar, i typed this really fast before leaving work)

Could be a fuel issue. I know my buddy's car would run real rough on hot start up when his fuel pump was taking a dump. Check fuel pressure at idle, normal driving, and WOT...if that checks out, go through the usual items. Fuel filter, o2's, and also check for vacuum leaks...

zero codes popping, (cept seatbelt)...also something else, which i don't think is related; there is a "whining" sound that seems to becoming from behind the cluster area of my dashboard as well during cold start, but it seems to be unrelated to the sluggish hot starts... i will check the fuel system, thanks!
