Takes a long time to start

My wife drives an '04 3.7L KJ and is having issues getting it started in the mornings or after letting it sit for a while. I tried to start it this morning when it was 32 degrees outside to see what the deal was. It cranks then turns over normally and the idle will go to over 1K rpm then drops and cuts out. If I kept my foot on the gas and kept idle over 1K it continued to run unless I decided to take my foot off the gas. It will only remain running with my foot off the gas once the engine temp got to half way. We had to replace the battery the other day and that's the only change that's been made recently. I was wondering if the IAC may be acting up. If so, how do I check it before coughing up cash for a new one. I also wondered about the TPS. I'm not a big fan of her KJ. I've always driven the XJ and they were easy to work on. Hers is a pain because everything is so tightly packed in and not easily accessible. Let me know what y'all think.

Have you checked the battery ? If they are going bad these can do some really funky things like not idling etc

The battery is not even a week old. The problem began after installing the new battery and the outside temp began to drop.

The spark plugs are two years old. I haven't checked them, but could/would that cause difficulty starting when the vehicle's cold? If it's the plugs, that's cool because they're dirt cheap to replace relative to a new sensor.

Not sure about cold starting but that would be first on my list when it comes to starting problems where the engine turns over.

It starts fine, but won't maintain idle once started and then craps out unless constant gas is being given. I'll check the plugs this weekend.
