Heater valve blew out, replaced it where it sat, drove home, it ran ok. Now it idles very very rough. Cleaned all electrical contacts i could think of. replaced mass air flow sensor, cap, rotor, coil wire. Cleaned throttle body etc. What could be the cause. Lost all water when the heater valve blew, car did get hot but was stopped immediately. Did it drop a valve? Please tell me it anything but something that serious.
