idle issue

First post! Recently, my Jeep (03 4.0) has developed an issue when trying to start. I originally thought it was due to the cold weather, but now it doesn’t want to turn over unless I press the throttle pretty far down. I cleaned the throttle body and the IAC, but I’m wondering if the IAC motor...
