All 92 troopers came with 3.2L Isuzu v6. Dohc or sohc. is it am Isuzu or GM motor? If Gm its a 1st gen 91, the below advice is valid for any idling stall though.

You may have a vac leak. My 92 had a split PCV Valve, ran great sometimes & just stalled at every light other times. Grime plugged the crack & it ran ok, sucked grime through & then air gets in bypassing the maf, int system sucks via pcv hose more & more unmetered air causing a nasty sensor mismatch between maf & tps & o2 readings... Thus a stall occurs.

Get a large can of o2 sensor safe carb cleaner & clean off all vac lines/seams/joints with engine warm & idling, I bet you find a spot that sucks in cleaner & chokes the motor out. Fix the leaking item (prickly by replacing) & it should run better.
