EGR P0401 - Exhaust Gas Recirculation Flow Insufficient

I may have figured it out. The passageway from the EGR to the intake
manafold was plugged and little air would pass. I pulled off the EGR
valve and the engine idled good. I put my thumb over the opening and
there was very little vacuum.

After using gumout and compressed air I managed to clean out the
opening. Now if I start the car with the EGR removed, the car barely
runs as should be. There is a lot more vacuum at the opening. I
buttoned it up and cleared the error code. We will give it 4 days and
see what happens.

Car is fixed. No more P0401 code

It was worth all the work. I learned a lot more about sensors and have
a better idea how to go about checking them now..

Thanks for all your help.
