Ive just went through 7pages of search, So dont harp on me to hard... Problem is when I got WOT or even more than half my gas pedal only comes up half way.. It doesnt hold the throttleboddy open or anything it just readjusted itself into another position.. I have to wait till I shutoff the engine then press the pedal to the floor for a second and pop it back up into regular position.. Its really annoying!!!!

 

I hate to have to keep saying this to people, but PLEASE post info about your car (year, trans, mods...). The signature is a good place for that.

Have you looked at the throttle cables at all? Do you have traction control? It could just be a binding cable.
