I think i finally got all of the air out of the system. I had to get a new radiator cap, thermostat and water pump. its been running well now. I have heat back in the car, but i think my heating issue was in the control unit. I replaced half of it and it works now along with experimented with two different operating temp thermostats. a 195 and 170. I am back to the 170 becuase everything performs better at the lower temp then the upper temp.
