Most likely a bad plug or coil, if the plug is oil-fouled you'll most likely have a gasket leak.

2000 cadilac deville. car runs fine, but when the Air is turned on is feels like it is misfiring and the engine light flashes, does this only when the air is on

Sir if the check engine ligh is flashing that indicates a PO300 code which is a missfire code. To determine which cylinder you will need a scanner to find out. The problem could be a failed sparkplug, a failed ignition module for that bank, a failed injector. At any rate it will require trouble shooting to diagnosis. Wish I could help more. Thank you

This is a code related to the air flow from the air pump (aka pollution pump) into your exhaust system. This air pump takes outside air and injects it in the exhaust stream after the engine to help burn off any residual fuel or pollutants. When P0411 comes up, the control module detects a lack of air flow either caused by a defective air pump, leaking/clogged air hoses, or bad check valves.

The hot air from your aircon usually has nothing to do with freon. I'm not sure about your particular car but usually there is a 3/4 inch valve near the rear of the engine to regulate hot water flow to the heater radiator under the dash. This valve can sometimes seize up. If it is a vacuum controlled valve, check that the vacuum lines are connected and not split.
