If you find that tube to the exhaust, OR a DPFE port, is blocked, I suggest
you change Gasoline suppliers.

The tube to the exhaust and the DPFE Ports are flowing just fine.
However, while the engine was idling I disconnected the vacuum line
going to the EGR valve and noticed that was not much vacuum going to
the valve at idle. Do you think it might be the EVR has gone bad and
sending enough vacuum to open the valve?
I removed the DPFE Sensor and also checked the lines running to the
riser tube from the exhaust. The rubber lines are clear and free of
cracks. The sensor had a little crusty buildup around the larger of the
two inlet tubes. I cleaned it and looked inside the inlet tubes. I
sprayed some carb cleaner inside the inlet tubes and re-assembled
everything, disconnected/reconnected the battery and went for a test
drive. The check engine light seemed to come on quicker this time than
it did from the last time. So, I guess it sounds like the DPFE sensor
may be bad.
