My idle is very low! where is the adjustment screw?
thanks,

Is this low idle a recent development? The reason I ask is that the cause of a low or unstable idle is varied and that pumping the idle air up to get the idle speed back up will mask the problem and may cause other problems.

- Check for vacuum leaks (disconnected vacuum lines, loose-fitting dispstick (i.e. missing O-ring at the top), loose oil-cap etc)

- Check for a crack in the VAF to throttle-body elbow.

- Check to make sure the large breather tube going into the elbow near the throttle body is a tight fit.

- Make sure the ignition timing is correct.

- Make sure the TPS (throttle position sensor) is adjusted correctly.

- Make sure the idle-air control valve harness is properly plugged in.

To answer your original question, the air screw is on the very top of the throttle body and is quite large. Again, I'd be loathe to adjust it; that screw is factory set and should never need adjusting... BTW, no matter what, don't touch any of the small adjustment screws on the throttle linkage.

Correct idle for the V6 is 650, +/-50RPM.

When I first got my 6 my husband brought it to the dealer to make sure the idle was right because it almost feels like it's gonna stall once it's warmed up. But they said it's normal.
