problem with my LS1, plz help!!!
okay first off my car is a 99` T/A auto. my mods are pacesetter LT`s with a H pipe and the exhaust goes all the way to the back(no cats/resonators just straight pip all the way back) and an intake and a custom tune for a local shop. i usually iht a consistant time of a 12.8 at the track, and this past friday i ran a 13.8!!!, my car is just bogging at the light. i used to have this problem, so i switched out the MAF and it fixed the problem. i changed my spark plugs/wires, put new O2 sensors, check the fuel pressure, and hooked it up to the comp. and it shows no miss fires, and i put a new MAF, but yet it`ll bog at the light really bad and wants to shut off. and if im driving down the road, it`ll bog and "miss" once in a while, but if i go WOT it runs perfect, its just at the take off and daily driving. any opinions on what it is?thank yo forany advice.
