Ha what he said.

Not sure what "changed the accelerated kit" means. Also you just swapped the throttle body, just one? Or both? Was it used, OEM replacement, aftermarket, bigger bore (EPS, Synolimit)?

Try disconnecting the battery and performing the throttle relearn procedure (search for it here on the forums).
