Car stalls after starting...Help!

For the past two days, my 2001 GT w/ 78,600 miles has been difficult to keep running right after I start it in the morning. After sitting in the garage all night, my car turns over as normal, but then stumbles and stalls. I can only keep it running if I keep my foot on the gas. If I drive about a block or so, it will run on its own.

Battery is original, still seems to hold juice, voltage reading is normal, and the "green ball" is still visible through the window. Alternator seems to be recharging the battery just fine, as I drive 1 hr. each way between work and home without problems.

Anything to do with the spark plugs, the fuel injectors, etc.? Any ideas? :(

I had a problem like this when I took my car to have the engine detailed, make sure there is a solid connection to the wires that attach to the top of that alternator. Sounds stupid but mine didnt make a full connection sometimes and caused the car to die.

if not.. is your fuel filter new? start cheap! replace it might need to be replaced anyways. My car died when I started it one morning and I cleaned the MAF and IAC and it ran just fine. Oh also my camshaft position sensor caused my car to stall out a few times, its a easy fix.. but it would throw some codes
 
I had the identical problem on my 96 GT, but only intermittant. Turned out to be the IAC. It was sticking closed after sitting overnight and wouldn't release enough to let the car idle. Took it off the elbow/plenum, used carb cleaner to clean out the build-up. Completely eliminated the problem.
 
I have the same problem...On cold starts it stumbles and dies when you first start it. Once its warmed up its fine. So you all are saying to look at the IAC?

It is a possibility. Generally a bad IAC will not let the engine idle at all. You can keep it running by using the accelerator but as soon as you let off it will die. It will usually take the IAC a while to kick itself back on. Mine would have to warm up for about 10-15 minutes before it would hold. In fact there was a noticeable change in the way the engine would run when it would start working. You could feel it smooth out.

Other things could be injectors, plugs, vacuum lines, fuel pump, fuel filter...I'd start with the filter.
 
I started having the same problem with my 2001 GT a few weeks back. It would stall on cold starts unless I had my foot on the gas. Once I rev it up to over 3,000 rpm it would idle without stalling. I cleaned my IAC and it worked fine for 2 weeks but now its starting to stall again. So I would think this would indicate a bad IAC. Should I go to ford and buy a new one or could it be something else? It’s even worse if it’s cold and damp out.

Usually parts are made in one factory then shipped to various distributors under their own brand. Not sure if the IAC is the same but I'd bet you could get the same one at Ford that you get at Auto Zone.
