Hi lately it seems as if my MEVI hasn't been opening consistently. Most of the time it has a distinct sound when opened as well.(hasn't been making the noise) The canister still holds vacuum and my RPM switch still green lights at the activation RPM.
The only other thing I can think of is the Vacuum Solenoid.

Do you guys think this could work as my Vacuum Solenoid?
