Stalling Problem -- Dealer has been able to correct
 
I'm having a similar stalling problem with my Jeep (2007 5.7L Hemi). Has been in and out of the shop since April. Initially went in for a bad MAP sensor that was causing the Jeep to run rough. They replaced the MAP Sensor. Then it started cutting out at speed (immediately restarts w/o my intervention) and stalling when idling (have to manually restart).

About three weeks before all this started, I had a tune-up done on it where the dealer replaced the spark plugs (copper) and fluids (oil, transmission, transfer case, f/r diferrentials).



So, far the dealer has replaced/repaired:
  • Map Sensor
  • PCM
  • Automatic Shut-off Cuircuit (switch in fusebox)
  • Wireless Control Module (because when it stalled: turning the key, it would just crank; turning the key to off and removing/reinserting, it would start immediately)
  • Checked Keys
  • Fixed Faulty Ground (From PCM to fuel rail)
  • Moved Coil Harness (to increase distance from the coils)
  • Checked for frayed harness behind the wheel well (this was reported as a problem by Chrysler)
Now they are:
  • Going through the wiring harness wire by wire to see if that was damaged when the plugs where changed.
  • Checking the transmission. Chrysler techs have reported that when the transmission fluid is changed there is a potential of an air bubble occuring in the torque convertor. This air bubble can cause a loss of power and the car to shut down when you're at idle. The techs saw this occurring a few weeks after the fluid was changed as the bubble worked it's way through the transmission/torque convertor.
But, they are stumped and grasping at straws for a solution. Any help would be appreciated.

I saw the EGR Article In the DIY section (which I will be doing myself) and it cures the symptoms you are reporting.

Check the EGR out! It might fix your problem! Plus you can do it yourself. What year and how many miles do you have on your WK?

i have a feeling it is your transmission. i used to stall all of the time, i changed the fluid and used the updated filters and it has not stalled once in the 18+ months since.

^ You know, come to think of it, last year when my dipshit brother killed my Jeep in a lake puddle and insurance replaced the motor, they did drain the tranny fluid. You know, because thats pretty impossible if they didnt. I havent stalled since. I do have that EGR probem though.
