Ford Focus Starts up, then stalls

I have a 2000 Ford Focus (2.0L SFI SOHC).  It has been running fine,
but I woke up the other day and went out to start it and it immediatly
dies.  I tried it again and it starts then dies.  If I constantly
press the gas pedal once it is started, it will stay running.  As soon
as I let off, it will die.  Sometime right after it dies, I hear what
sounds like a poof of air from somewhere near the engine.

I have already changes the air filter & spark plugs.

I'm not very savy when it comes to fixing cars, but would like to fix
this myself if possible.

Any ideas what I could do to fix it?  I greatly appreciate any help!
Thanks.

clean the battery connections just to make sure there is not a loss of
battery power and the computer is not losing it's memory

It could be a blocked catalytic converter.

Only a guess.

How do I check if the IAC valve is shot?  Is it something that can
just be cleaned, or does it have to be replaced.

Also, could it be the PCV valve or fuel filter?  I can't seem to find
the PCV valve??

Took out the IAC valve, cleaned, then reinstalled.  Put new fuel
filter on.  Still no change.

I did notice that when I take off the air tube from the air filter box
to the engine and then try to start it, it idles about 8 seconds
longer before it quits.  This would indicate to me that a lack of air
is causing the engine to stall???  I hate to drop 70 bucks on a new
IAC valve if it isn't the problem.

Still can't find the PCV valve.  Do all Focus's have one?

Desperately need help!!!  Thanks.

Are you taking off the main air inlet, or the PCV line? Taking off the main
air feed shouldn't have any effect. Can you get the car to run if you
manually open the throttle?

I'd put my money on the IAC.

Yes. It is on the side of the engine down under the exhaust manifold.
