Well, just to update for search puposes:
I picked up the DPFE Sensor - Part No. F77Z*9J460*AB - from Terry at Sentry Lincoln Auto Group - The black plastic case - Installed it today.
Let it idle after plugging battery back in, idle settled down. Drove it around slow and fast - car drove fine.
Let the car idle for about 10 minutes - idled fine.
Shut car off. Turned back on after a few minutes, drove it around again and again...let it idle. No CEL yet.
FWIW - The DPFE Sensor that was originally in the car - The one with the Aluminum Casing - has a Part No. F48E*9J460*BB
The configuration of the Sensor is a tad different - Both vacuum hoses that connect to the New Sensor - are in front. Where as the old sensor - One is in the rear and the other in the front.
Anyway - Will update if CEL comes back.
Later.
