Hey does anyone know how to adjust the rpms of a 92 4.0 explorer when it is idling? is there some sort of screw near the accelerator cable or what? thanks

The idle speed is controlled by the computer via the idle speed control motor/idle air control valve. I don't think there is any provision for adjustment.

Mine idles at about 600-700 RPM in park, using the in dash tachometer.

Adam, if your idle is off try cleaning the IAC valve on the driver side of the upper manifold--looks like a long cylinder attached by two or three bolts. You can use throttle body cleaner or brake cleaner, just be sure to get it all out and let it dry. Next I would invest in some good plug wires. When I got my Jacobs my idle dropped to 600-700 range and became very, very smooth. About $50 with lifetime warranty.
