That would be the answer instead of buying alot of guessing parts.

Yes but then he doesn't get to waste a bunch of money on new parts! oh wait...

well ive talked to Don, he had a few ideas but i think thats where we left it, at needing a retune...i dont have $500 to fix an annoyance...so im gonna wait til i mod it and actually need the car tuned

don did the tune on the car now.

Nah, all you need is an LT1 brotha!!!!!!!!

Just thought about this i dunno if the tb has an idle screw under the linkage but if it does give it a few turns

i usually just bent the tab. alot easier to get at then the fucking 5.5mm set screw. just make sure you dont bend it too far and the tps reads any % over 0!!

If you're ever near worcester I can scan it for free with my scan tool and see whats going on but other than that, I leave it to Don.
