base idle adjustment 700 1988

posted by  someone claiming to be aaron on  Mon Dec 4 20:35 CST 2000 [RELATED]

Hey all,

I heard (from somewhere like a faq) that if you weren't game enough to ground the wire that disables the IAC, you could pinch the hose going from the air intake pipe to the IAC......when i pinch the hose (i mean REALLY pinch - i.e. no air goes through) the car seems to REALLY sputter for about 3 seconds at what i'd guess to be somewhere near 150rpm, then it dies...... The IAC appears to be hunting a bit, and i figure that the base idle being wrong would make it work hard, correct? And, to adjust the base idle, is it okay for it to be under the 700rpm base idle speed, so long as it isn't over? (obviously if it is over, the IAC can't compenstate!).. Also, do i need any other equipment (beside an "engine analyser" (that contains a tacho, etc)? I am sorta guessing all i really need to do is adjust the black screw (i know this won't make any difference to the idle, as the IAC compensates as you adjust....).... does this all sound good? if so let me know! THNX ALL!
