I'm just getting back into the dsm scene, I had a 90'GSt before, noe I have a 98GST, last sunday it started to run rough, the rpms bounced all over the place, then it backfired a few times and died. I had to have it towed home, so far ive replaced the plugs, plug wires, coilpack (it was bad) and the fuel filter. it runs now but the idle is a bit unsteady and i am getting occaisional hesitation on acceleration. its stock so far, I've just been getting the maintanence stuff done before I do any major mods.Any Ideas? I'm wonfering if it could be the IAC valve.
