Aos

All,

As a follow up, replaced the AOS today for $200 Canadian (tax in) and everything is good to go. No more CEL (related to O2 emissions/sensors etc), no oil pressure light flickering at low RPMs.

There was a tear in the Diaphragm inside the AOS...once replaced, the whinning sound was gone as well at 2200 RPM...

Thanks for the help!
