OK, thanks. What a PITA this erg thing is, wish I could just disconnect the darn thing....

Another idea I found:

Before you try to clean the valve which probably os ok.... test it 1st. Have the engine at idle.
Disconnect the hose from the valve. Apply vacuum to the valve with a hand pump if you have access to
one. If not, you can get manifold vacuum from the nipple on top of #6 intake runner.
With vacuum opening the egr valve, your idle should be very rough.
If yes: you have a tired catalytic convertor.
If no: 9 out of 10 times, the tube is plugged between the valve and intake.
