yah I have no idea why the gasket does NOT have the word UP on it. as some do.
said that. you blocked the .050" orifice and ran head dry.... never good that.
that screw is never touch screw and when new is black pastic cap there blocking you
the this TB top rear (see black cap there, that hide the idle air bleed screw, only this is adustable.
the engine only idle at 800 if water temp hits 180 at the 150f cross over the idle goes to 800.
water temp is always first check. then water flow must actually pass through the bottom of IAC , water jacket inside it, (TB base bottom ISC)
the TV throttle valve is always closed at idle 99.9% and set at the factory I think at .0005" gap so the TV can not jam,, but flows no air at all the TV, only 3 things flow AIR.
IAC therm (only cold)
ISC electric (hot idle PWM controlled by ECU)
and bleed valve. (sets idle PWM duty cycle to 50%
the stop screw is 1 time ever factory setting.
