1995 Bronco 5.8L 4X4

Can someone help me with this?

On cold mornings, the engine misses. If I drive before it gets warm it lugs
and I can even hear what sounds like a backfire. It idles at about 1300
rpms, then returns to normal after warmup.

At other times, while waiting for it to warm, the idle will drop to 500 or
so until I give it gas, else it might die.

Any input would be appreciated.

Thanks.

Could be a dirty or clogged IAC or a EGR valve
that is gummed up. I am betting the IAC . they won't
throw a code and you can get em at autozone or the
like for about 50bucks and you can put them on pretty
easy.
