Removed valve from car. It was easy to remove. Tested with 12 volts and nothing happened, no clicks. Sprayed "Blaster" into both sides and waited overnight. The valve freed up and I placed some Marvel Mystery Oil into both ports. Waited one hour and reinstalled in car.

It's alive! It's alive! I can feel the valve pulsations of the ECU pulse modulation. The valve is mostly silent but feels like a heart beat when you hold the valve.

This should remedy the EVAP purge flow fault PO441 code.

Hope this lasts. It could be the problem with these valves is a build-up of fuel varnish.

Thanks for all the help
