No heat in cold weather

Does the vehicle reach normal operating temp? On a warmed up engine what is engine temp in degrees F? Are the heater hoses hot? You have good coolant flow through the heater core? Could be problem with temp door, under the dash?

Won't restart in Warm Weather

The first thing you need to do is run the system for fault codes, any Autozone will do this for free, ask for a OBD2 fault code test. If no codes show check the fuel pressure next time this start problem occurs.

F 150 2004 stauls during the winter-summer months no stauling

The stalling, if you are talking about when the engine is cold, is due to a failure of the "Cold start routine". Should this be the case, the defect is due to a temperature sensor failing to send a signal or the PCM failing to use the signal.

Now if this stalling is when the engine is warm in cold weather, it can be due to the ISC(idle speed control) solenoid. One reason the stalling is reduced in the Summer months is the A/C has an idle speed step-up which works when the A/C is used.

Another part which can cause stalling is the "Cam Phaser" in some Ford designs. The A/C step-up may mask this problem too. This is a problem in 2 camshaft motors. It requires more intensive inspection. Try the cheaper causes first. The Cam Phasers would be expensive.

83 Rx7 stalls when cold unless I keep applying pedal pressure

these cars are carburated motors and need around 10 minutes to warm up because they operate at higher temperatures.
