warm weather stalls??

:confused: what would cause engine to stall when weather warms up? 96 ford E--150.....has nothing to do with engine temp, which seems ok, but when outside temp warms up it runs like crap. i'm leaning towards a sensor or filter? if anyone has had this problem i would love to know how you solved it....THANKS

Warmer air can hold more moisture (humidity). It may be that this moisture is affecting frayed or corroded electrical wires or even the spark plug wires.

I'd start with checking the spark plug wires. Run the engine in the dark with the hood up and watch for any sparks/light. If you see any, you need to replace the wires.
