At speed I have no heat or minimal heat and engine temperature is cold. When I'm parked the engine temperature warms and I get hot air? What is causing this?

It's likely the thermostat is weak. Try replacing that first.

I tapped where the thermostat is with the butt end of a ratchet and it works a little better but not great. So more than likely is the thermostat right?

It's common for the thermostats to stick in the open position on these engines. Remove the thermostat and inspect it.
