Matt, here's more.

Warm your engine thoroughly with ISV connected. Shut the engine down,
disconnect the ISV, start the engine. Adjust the idle screw until the
RPM is at 850-900 RPM. shut the engine down. Reconnect the ISV. Allow
the engine to get colld. Restart the engine and note the RPM. Should be
1000 to 1200 rpm. Watch the RPM as the engine warms. RPM should drop to
850/900 RPM. Turn the steering to the stops right and left, RPM should
increase. Recenter the wheel and RPM should drop to idle.  Turn the AC
on, RPM should increase. Turn off the AC, RPM should drop to idle.

If these things happen in the order described, all is well. If not, you
will need to do more sleuthing.

Good hunting,
