Have you ever cleaned out the throttle body (Intake)? If not do that first and see how it works out. I have done seafoam on my truck and throttle cleaning on a normal basis and i have to say what a dam difference.

As for the 4x4 that might just be a sensor going bad. Sorry cant help to much i have a 2002 doesnt have stability track.
