Our 2005 Jeep Grand Cherokee with a 5.7 liter hemi engine started fouling (stalling out).
The ESP light was flashing. Finally the check engine light came on with a code P0355. Had to take it to the dealer and their diagnosis was the crankshaft positioning sensor was bad. Replaced it and we are back on the road. Cost: $45.75 for the sensor + $47.50 for the labor.
