Im really concerned
I recently got my Hooker Super Comp. Longtube Headers installed with an offroad x-pipe. Behind that I have a magnaflow exhaust. Ever since I pulled out of the garage that did the work, I have had trouble keeping it running when I start it up. If the motor is already up to temp, it starts fine. But cold starts suck(and I'm in Florida!). I can't get the idle to hold until i drive for a while and get up to normal operating temperature. The idle will even jump up and down at stop lights until it warms up. When I first start it, I have to feed it fuel for like a full minute for it to hold an idle, and a s**tty one at that. The car has only 36,000 miles on it and ran absolutely PERFECT before I got the work done. What could this be??? Backpressure problem? IAC problem? Header Leak? Also, the check engine light pops on from time to time. Could my MIL eliminators be failing already? I hope to the good lord that someone on here can help me out. Thanks guys, I appreciate it. Sorry for the book.<IMG src=smileys/smiley19.gif border="0">

How long has it been out of the shop? It will take the pcm some time to relearn its idle strategy after performance adders have been installed. As for the check engine light, its pretty much a gaurantee that the O2's are kickng the light on. Might be you got some bad MIL's.
