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,

John Rodgers 88 GL Driver
