When started hot or cold in park or neutral if you tap accel rpms go up to 2.5 or 3k and hangs there when in drive brake on 750 does this until you unplug the idle air control valve then idles down to normal.

Try cleaning out the idle air control valve and see what happens-also test the MAF sensor-
