Figured it would be the DPFE sensor, so went to Oreilly's first. They didn't have them in stock, so went to Advance next... same thing. Finally to Auto Zone and the very same thing. Finally asked why and well i'll be darned... the DPFE sensor is now a dealer-only item.
Funny, the last time I replaced it it was still being carried by the auto parts stores....
And I absolutely DREAD going to the dealer to get one...
