03 Mounty has randomly died twice since Monday...

[shadowless127]

Monday she died at a stop light randomly without any sputtering, no rough ide, just died; she started right back up. Today she died as I was pulling out of a parking spot. Put it in reverse, let go of the brake and went to hit the gas and she died. Put it in park and she came right back on.

I had no SES lights, no blinking O/D lights, no messages in the message center.

I don't know what else to do.

Sounds like a dirty IAC or MAF sensor.

Hot weather + sticky IAC = stalling truck

What is the IAC?

What is the IAC?

Idle Air Control. It is a valve that regulates bypass air (air bypassing the closed throttle plate) to control the idle speed. If it sticks closed, not enough air is let in and the truck will idle too low and may stall when the truck is shifted into R or D.
