Hi guys,this little like screw on the opposite side of the throttle body cables,next to the iac looks like a bleeder what is it fore ???
I have some idling problems and I was wondering ??
thanks
There is a screw on that side used for idle adjustment, so I'm prettysure that is the one you're speaking of, but wait till someone else chimes in, my poor car's in storage and I can't go confirm this for you.
Its the IAC bleeder screw. There are lots of good write-ups on here that describe how to do it correctly, you need to unplug the IAC connector and adjust the idle with this screw, etc...
Hissin seems to be the resident expert on idle setting, I'm sure he will chime in on this one...
This is from a post from a different thread written by R.J.:
"Try resetting your idle like this:
Begin with a cold vehicle. The idea here is to get the car to a firm cold idle with enough air bleed capacity left in the idle circuit for IAC adjustment.
The idle stop should be set first. Back out the idle stop screw, away from the bell crank arm, until about 1/2 turn past the point where it no longer makes contact (blade fully closed). Using a 0.010" feeler gauge, tighten until gauge just drags between screw and bell crank arm. Remove feeler gauge. Tighten screw exactly 1 1/2 turns. If the screw is very loose, put a drop of loc-tite or silicone on it, so it doesn't work out of adjustment.
Now remove the connector to the Idle Air Controller (IAC) just on the other side of the throttle body. Start the car and allow vehicle to warm for 2 minutes. Give a small "blip" to let it settle. If it is having a hard time staying running you may have to get an assistant until you can get to the front of the car. Now open or close the air bleed screw (CCW opens) next to the IAC until the car idles at 575 to 600 rpm. For guys with aftermarket cams and an EEC tuner, you might want to idle a bit more briskly, say 650 to 675.
Obviously, this rpm range is by what the car and driver wants...IE, no set idle speed, whatever works for YOU.
Turn off the car. Now count the number of turns clockwise to close on the idle air bleed screw. If it falls between 1/2 and 2, it's okay, now reverse it out the same number of turns. Log the number somewhere in case you need it for the future. Reconnect the IAC. You are done.
If the air bleed screw is above 2 turns, it's a good idea to tighten the idle stop screw another 1/2 turn, and then repeat the idle setting. If it is below 1/2 turn, then loosen the idle stop screw by 1/4 to 1/2 a turn, and repeat the idle setting. Be sure to put another drop of silicone RTV on the stop screw if it was disturbed. Reconnect the IAC. You are done."
Hope that helps. If not, search "resetting the idle", this topic has been covered alot.
