my 93 22re does not kick down after warming up, the engine has 198,000 miles on it and runs good otherwise. i changed the plugs, and cleaned the k&n drop in filter and ran a can of seafoam through it. can i adjust the idle my self or should i try other things first, i allso need help with the idle screw location thanks.

 

there is an idle screw on the left side of the throttle body.. its a flathead screw.. screw it in to idle the engine down
