I have an 07 Grand Cherokee Limited with the 5.7 HEMI. I have been getting that intermitten stalling problem. Kind of what i read from other ppl online but this is whats different. When i am driving down the road the Jeep will just stall out no warning at all. Usually i shut the ignition switch off completly and it will start back up and drive fine. Today in Michigan we had a blizzard and it stalled in the middle of an intersection. Pretty embarassing and finally started back up. I work at a gm dealership so i went to work and scanned for codes and it said low barometric pressure. I dont know how to fix this one. Later on tonight i drove it and it stalled and wouldnt restart for approx 5 min. The Jeep has 75000 miles on it . Before winter i replaced the battery, all 16 of the plugs and insulators, air filter and fuel filter also . If anyone could help me with this crazy problem I would appreciate it. My plan wass to buy a new srt8 Jeep this spring but this scares me to spend that kind of money and possibly get the same issues after reading on these Jeeps. Thank you. ANd this thing typically doesnt store any codes either.
