Heater throwing out cold air put in a new thermostate work for two days throws out cold air again what might be wrong? Also when heated up the truck dies. At a stop light it also chugs like its going to die. Also when I step on the gas it should be at a steady speed and it kicks down or outin speed like the gas pedal is sticking.
