My GTP starts, runs great for 30 seconds, and then it runs like crap and sometimes dies for 30 seconds and runs great after that. Any ideas????
Speed Daddy headers or 3" Downpipe? Witch is better? I have a 3.5 pulley, K & N with AIR Box mod, Ubend Delete, Stock exhaust. My car only runs 14.55 @ 93 mph
