maybe answer on random 4.0 stalling.

Been reading about random stalling on 4.0 then starting back up. Nobody realy had an answer except changing every sensor,ecu, ect. I started with crank sensor then went to throttle body and sensors. Still no fix, so took to machanic. He Finaly found a loose connection on wire harness out of fuse box in front of battery. Drove around today and no stalling. Will drive all day tomorow and see if it is fix. Fingers crossed.

Well, not fixed. Seems like a common problem with no sure answer. Getting ecu next. No codes at all, thought I had a bad cel bulb, changed that and still nothing. Betting on ecu.
