Low idle... screw adjusted

[DrLove'sKuDang]

no matter how i adjust the idle screw, my idle is still lower than i'd like(650-750). even when i take the screw completely out, my idle is still below 900. what else could be causing this low idle? btw, this is when completely warm.

I don't think that screw is for idle adjustment. That screw just opens your valves to suck in more air. If you have a short ram intake, you could hear the filter suck more air when you screw it counter-clockwise. When turning the screw clockwise, it sucks in less air...somebody correct me if I'm wrong?
As for idle adjustment, you will need to adjust the two nuts on that wire that runs along the top of your intake manifold...again, somebody correct me if I'm wrong?

That screw is for idle adjustment. You should tighten the throttle cable until it's tight, but not enough to open the butterfly(you hear idle go up).

The procedure for adjusting base idle is in the Helms/Chiltons Manual, I'm not gonna type it out here.

yes, what blue said...the screw is for idel adjustment. Also one thing that happend to me was my MAP sensor wasn't plugged in correctly (wrong vac line). Make sure you're map is working correctly and vac's are all good.

Im just curious as to why you want to raise the idle. 700 rpm seems fine to me.

1200 is my recommended idle speed.

you are suposed to disconnect the IAC ( i think ) and with the car running turn it , then turn the car off and connect Iac ... then turn the car back on


its in the MCleans manual if im wrong,.. cant rember

The correct procedure in the HAYNES manual says :
1) Start you car and let it warm to running temp
2) Remove plug from over screw
3) Disconnect IAC connector then turn screw to adjust your idle
4) After achieved idle necessary, turn car off, re-connect IAC connector, remove 7.5 amp backup fue from fuse box for 10 - 15 seconds, re-install fuse then start car and check idle.
REPEAT PROCEDURE UNTIL IDLE NEEDED IS ACHIEVED!!
I know because I did on monday, my RPM is now at 850 RPM which is cool!
