Idling Issues

[kona0197]

New to the site, happy to be here. I have a 2006 Explorer. Has the V6. A few weeks ago we replaced the battery. Ever since that day the truck does not want to idle at all. Battery and alternator have both been tested and both passed with flying colors. Still runs and drives fine. I was curious if it's an easy fix like a reset button somewhere or a fuse I need to replace or ??

Interesting. Ususlly when the battery is disconnected for more than 10 mins it has to do an idle relearn, so that may be part of it. Just to check you didnt accidentally mix up +/- right? I assume not, but figured Id check! And welcome!
