Heater valve blew out, completely shattered, replaced it and car ran great from where it broke down back to the house (about 50 miles). Now when you start the car it idles very very rough. Idles rough at lower speeds, doesnt cut off but acts as if it may. Cleaned all contacts I could find, replaced cap and rotor, cleaned mass air flow sensor etc etc etc. Almost acts like it dropped a valve.... I hope not...please tell me its not that...
