Everytime I wound come to a stop with the A/C on and pressing brake pedal my idle would drop. If I engaged the E-brake while at a stop instead of pressing down on the brake pedal, idle would level out.
Just cleaned the throttle body and that threw my idle up to 1200 rpm, tried to readjust the idle air screw and nothing. Almost backed it out all the way and still nothing. (Counter clockwise "INCREASES" RPM)
Finally just removed the screw and it was covered in soot. Cleaned it off and cleaned screw hole. Made proper idle adjustment and no more idle drag under load.
Now just have to get another o-ring for the screw.
