Taurus that Dies Randomly on Idle

#1

I originally took in my Ford Taurus for a squeaky fan belt. They replaced the Cam Synchronizer too, and a new DPFE valve. Then it started dying on me in idle - very randomly, about 2-3 times per week. Since then I have been back twice, had engine tuned and idle motor replaced. And it’s still randomly quitting on me when I come to a stop.

Year, mileage, and anything else you can think of. All Tauruses are NOT the same.

What is a DPFE valve?

We’re not mind readers.


#3

Could be the idle air control (IAC).

Consider the A/C compressor. It may be dragging the idle down. When you feel it about to stall, if you have time, turn the A/C off, and note any change. Also, if you have time before it dies, shift the automatic transmission to N. Any change?
HOW does the engine stall? Slowly, suddenly, bucks?

I don’t know what the DPFE valve is!


#6

It stalls in a hurry, no warning, just that I am stopping at a red light or slowing down to park.

Thanks - I’ll tell the mechanic this week
