I had an 84 Bird. There were 2 places to set the idle. If someone has worked on it or if the first setting fails, it can give you that problem. Check for a loose vacuum line going to a carburetor part. Sometimes putting in a new air filter will cause the vacuum line to fall off.

The next thing to check is an EGR valve that is not closing. This will cause the engine to stall at idle.

Finally, if you need a diagnosis the Autozone or O'reilly auto parts people will scan your car for free. They may be able to sell you a part you can put on yourself to solve the problem.
Good Luck

    The same thing was happening to my car and it was the loose vacuum hoses. That just saved me alot of money. The mechanic said it was probably a bad neutal saftey switch. :D

Transmission issue w/Ford Taurus?

Sorry to tell you this. You have an AXOD/AX4N Transmission and it is going bad on you. Soon, it is going to strand you on the road.

Some people will put Lucas into their transmissions to extend the life of the Transmission but there are people who do that and cause it do DIE!!!! and I mean Immediately.

I am sorry to give you the bad news but at least it is Honest...

94 Ford Taures dies in reverse

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.

duck tape on the air intake. I just fixed mine. There is a crack on the intake that lets too much air in when you put it in drive that makes the car stall. Try it it works.
