Too much air flowing into the intake causes the engine to lean out too much air in relation to the fuel and misfire. At an idle, the PCV valve restricts air flow, to reduce this problem. At high manifold vacuum...

Trapped air can cause both overheating, and lack of cabin heat, so hopefully after you replaced the thermostat, all air was purged from the cooling system. Assuming the cabin heater control valve is functioning, a common reason for no cabin...
