As far as the motor, it sounds like it is going bad. The heat issue is different. Make sure the engine is running at a normal operating temp, make sure the coolant is full, feel both heater core hoses when the engine is hot, running, and the heater is on. Both hoses should be hot. If they are, chances are the blend door needs adjusted. If only one is hot, flush the heater core.
