Shiroelex said:A TPS is $32 at Autozone, and you can return it if it doesn't cure the problem, as long as you have the receipt. I'm thinking your problem is something else, though. Are you sure all of your gaskets are sealed good? Like that 'reusable' one that goes between the upper and lower? Also, is the inside bored out too big, to where the throttle blade doesn't seal the hole completely anymore? I've seen where the bore was too big, and there was a small gap at the top and bottom of where the throttle blade shuts. Take a peek inside; that might be the problem. Oh, also, if they bored too big, or some metal shavings went somewhere they weren't supposed to; that might cause a problem.
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.
