Usually a high cold startup idle means that your WUR and AAR/AAV are working right . The AAR should not come into play in a hot start situation, so maybe there is something wrong there.

If you knock the plug on the WUR I think you will lower the control pressure. This usually enables the idle speed to come up to the higher speed as demanded by the AAR, and will only make your symptom worse.

Have you checked your warm control pressure? Have you looked for vacuum leaks? Have you tried disconnecting and plugging the decel valve and line?

Does the engine feel unduly rich or lean? Does it rev to redline freely, or too freely? I am thinking your mixture is off. You may be too lean. Try richening it up 1/8 turn and see what happens.

Can you turn your distributor rotor easily, and does it snap back when you let go? Is the dist itself fixed, and not rotating?

By the way, I'm not a pro...just a guy w/ one of these cars.

You can also try lowering your idle speed and see what happens under the varying conditions.

If you don't have pressure gauges, try the mixture setting first.
