Well my wife to be called me the other day from work and said her trooper started to stall at idle and the check engine light came on. I got a scanner and checked the codes.
Bank 1 and 2 lean. I monitored the o2 sensors and bank 1 was switching normally but bank 2 was stuck at 89mv. Bank 2 sensor 2 was also low. Fuel trims on both banks was +40%. I sprayed some brake cleaner near the intake gasket and as soon as I did the 02 sensors would go full rich. You could actually hear it suck in the fluid. Just thought I would throw this out for everyone. Perhaps you could use some of the info to give to your dealer if you have a stalling concern.
