loosen the two screws that hold the tps and turn it while idling ,you don't have to remove it just a 1/8 turn

is the vaccuum hose still on the vaccuum modulator and routed to the throttle body?? might replace that hose just to be sure.

When I push on gas it sounds okay but as I go faster it seems to reeve up and then when I brake and slow down or stop it goes back to normal
