idk about the pedal problem but one time installing an intake i had a bad gasket on a runner and had alot of unmetered air going in the engine making it rev high the instant the motor turned over. New intake gaskets and i torqued it down and MY problem was solved.

sounds like a vacuum leak to me. check all around your intake, did you separate the upper shell from the lower? it might not be seated on there correctly. I know i never separated mine, and somehow the upper shell bowed out from the upper after initial startup and i had a crazy leak.

never tried it but i will see what happends
Have you checked the throttle cable? Try removing it and letting it idle and see what happens! just a thought I highlighted what makes me think throttle cable. I know my cable is a tad loose so at times when I do some WOT runs it wraps around the throttle lever and I get the cruise control effect although the thottle works it just feels different when pressing it and it keeps my idle high but I have a LT1 cable so you might not have that problem.
checked everything that i can think of even replace the idle control vavle and also change the Camshaft Position Sensor. if the tps relearn dont work i might just buy a new 1 and see what happends.

And pretty much I dnt have to hit the gas cause it does it for me, fukk I hate my car right now. Well tune here I come.. thxs everyone for the help..

Problem is you now have a much larger throttle body than stock, so even at idle openings it's letting more air in than the stock one does. In short, you'll need a tune to correct the 'hang'.
You also need to make sure you have no vacuum leaks. Double check every hose you touched. A 3k hang is pretty high; I'd bet you have some form of leak somewhere.

a)Is your throttle body set screw adjusted correctly? It might be keeping the blade from closing completely.
b)Sounds like your throttle body spring might be binding up as well. Have you tried opening the throttle by hand?
c)If so, does it still feel stiff?
d)What throttle body are you using?

+1 for vacuum leak, try MAP sensor also, after I installed mine, I forgot to wait a little bit after I put rtv on the MAP and turn the engine over, the rtv cover the grommet and messed up my MAP, oh and when my MAP was broken I had the exact same problem like you. Really embarrasing being in the traffic light and your car rev by itself.....
