Poor Idle

I have a '99 V8 Explorer. Recently when I start the vehicle first thing in the morning it idles low and sometimes stalls. I have noticed what sounds like a quick backfire when I start the car occassionally. Today when I started it at lunch the CEL was illuminated. Any ideas on what could be going on? IAC?

Mason, not sure if it is... but in mine I had a poor idle because the throttle body was old and the seals on it were letting too much air in. It did eventually throw a code for that.

The CEL is off this morning and it's idling fine. The problem seems to be intermittent (duh).

Clean the throttle body and IAC, you're going to have to eventually anyway.

Still pull the codes as they should be stored unless you cleared them with a reader or by disconnecting the battery.
