OK................. Mon am - not so good. Because of heavy traffic friday evening, I was only able to test drive it @5 miles. Diff noise is gone - that's good. Check engine light not on. My wife meets me later at the dealership. She gets in and starts to follow me home....................we don't get 3 miles. She calls me and said the check engine light just came back on.

We then have to navigate over 4 lanes of rush hour traffic to hit the next off ramp. Takes us 40 mins just to double back 3 miles to the dealership. They appologized and gave us another loaner, service dept is closed over the weekend and nothing will happen until today.

I strongly feel that the rear oxy sensors are lazy and that is what is causing the C/E light to return, but since it is a symptimatic code, Jeep warranty will not address (I believe)
