My Ford Taurus is dying while driving and ideling!

idle control valve

check oil level in transmission
what is it manual or automatic or CVT ?

i have seen many strange things happen with the distrib cabs on these

Does it run if you give it gas if so check the iac motor if not check fuel press at idle and 1500 rpm should b 40-50 psi

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????21

Do you have spark after it dies? Possible ignition module.

If it was an Oxygen sensor it would most likely cause the CHECK ENGINE LIGHT to come on.
I would check the spatk plugs and condition of the plug wires first.

Check the coil for a white ash look any where on the coil. This is an indication that there is a crack in the case and its firing thru it. this can cause that problem. one other is the pick up coil in the distributor. these will not show anything. theres no way to check because when they are cool, they will test fine, but when there hot they just die. when they cool down , they work again

change the drive belt on the car if the car has over 40,000 miles and while you have the belt off have the alternator tested as while as the battery you may just have a bad cell in the battery

How is the car when put in drive? Does it almost stall or does it run fine? Almost sounds like a transmission problem. Reverse and drive put the same exact load on the engine when sitting still, so it seems unlikely it could be anything but a transmission problem. Maybe the transmission range switch is out of adjustment or bad.

If there is no check engine light on I would go the local auto parts
store and check out the TP sensore first and then the Mass air flow...
