The DPFE (differential pressure feedback EGR) sensor tends to fail. The DPFE sensor monitors function of the EGR valve by measuring pressure changes in the exhaust gas recirculation (EGR) system. Symptoms of a failing DPFE sensor are hesitation or stumbling when driving along with illumination of the Check Engine Light.Google+

poor gas mileage, poor idling- acts as if it will die and no power. Thought it might be catalytic converter at first but decided to check out the DPFE sensor first.

check engine light appeared and it is the ERG not getting enough pressure or the sensor is bad. Autozone did the diagnostic for free and now I am reading on the web how to clean the valves and try and fix the part.
