Ok well maybe i'll try buying a TPS today and seeing if that will fix the problem. Also, i never bored/ported the Throttle Body. Its still "stock" for an FRPP 70mm T/B. The only thing i ported out was the plenum. I also air blasted, brakecleaned, air blaster, brakecleaned, air blasted & air blasted some more before i installed that plenum. So there can't be any metal shavings anywhere... Intake gaskets MIGHT be off, i'm pretty sure they are not, but if by next weekend all else fails, maybe i will recheck the gaskets. Dont think that is the problem, nor do i think that would affect the idle or hanging RPMS.
