Question about 1994 Jeep Grand Cherokee
Open up the air filter and clean the element.

Hi! Looks pretty much a MAF (mass air flow) sensor issue. The MAF has big contribution on engine performance specially on the idle and vacuum supply. When the MAF is faulty you can experience an unusual idling, rough riding and sudden stalling. Once the MAF is replaced you'll be good. Hope this helps and thank you for using Fixya!

Engine stall or RPM fluctuates
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
