sorry but this is a little long. ok so since Rita hit down here i came back and my trans am survived with no damage. the problems i was having with it before was it warmed up then ran crappy. so i started to fix em all, including rethreading the hole for cylinder 3, new opti, new wires, new plugs, new coil and ignition module. that cost a whole lot more than i wanna discuss, but if you live around beaumont dont take your car to lonestar performance. they dont know shit and they cant get any of their stories straight. i finally get my car back and it dies on my in traffic. wtf? call lonestar, cuss em out a little and they pick my car up and i get it back a little later. still runs like shit. so i get the alternator changed and that keeps it alive. finally at long last i'm broke and the SES light decides to come on, O2 sensor. get it fixed and it runs great. that was cool for awhile. a couple weeks later i'm driving to my wedding and it starts to act up again. only now it runs bad while warming up then when the SES light comes on and it's warmed up it runs ok.i just got some exhaust leaks welded shut where the header slips over the y-pipe. did nothing for me. it shoots out black smoke bad when accelerating. getting out of first gear is when it feels the most sluggish then it accelerates better in the gears after that. i need to get the SES light checked again but havent had time. my car is an A4, 2.73 gears, has LT4 hotcam, heads machined to lt4 specs, full 3" exhaust with no cats, longtubes, nitrous but i never use it anymore, cold air intake, descreened maf, throttle body airfoil, and still on stock tune. i've been wanting to get a new cpu and some 3.42 gears in there but that keeps taking a back seat to everything else unfortunately. anyone have any suggestions or ideas to help me out. i miss driving the thing but i'm tired of putting all my money in it and getting nowhere with it but i refuse to sell it.
