working on a 2008 Town & Country has a 3.8l engine. Setting P0300 vehicle is not misfiring and looked at misfire counter and have no misfires on any cylinders. What usually causes this. vehicle also stalls out.
Chicken and egg ? Could it be the P0300 is being triggered because it is stalling rather than a misfire causing the the stalling. Freeze frame might help .. Stalling at junctions could be down to the IAC or throttle body or even the pressure sensor on the power steering.

found a plug wire that was arching outside of the spark plug wire. had a theory that when it was firing out side of the wire it was finding it's way to ground and stalling the engine. To test the theory I hooked a test light to.battrey negative and when the spark jumped out of the wire I stuck the tip of the test light to the spark and the engine stalled.
