I just recently did a header install on my trans am.. i have not had it tuned yet.. i have been experiencing one major problem...the car alot of times will not accelerate when i give it gas and then when i slam it it kicks in and runs fine at WOT. but if i start driving regular again it start to cut out again..any ideas or suggestions?

 

probably not enough info on car. what year, etc.
sounds like something simple like a loose or burnt plug wire, or something that was nicked when the headers were installed.
may also want to try in the gen III sec.
