i'll have a look again in the morning but i had that throttle body torn down and blew all the cavitys out with air before reasembly,,,but a double check wont hurt...i'll let ya know the verdict thanx again

 

ok so i tryed cleaning that idle adjustment screw cavity and no dice...still idle surging and bounceing...i went out to the local used parts yard and bought a used throttle body intake with denso sensors and iacv...put it on and.......same problem,idle surgeing and bounceing,so i know its not anything on the tbi or iacv...any other suggestions,still freaking stumped!
