I believe that device is the purge valve for the vapor recovery system, and I think it buzzes periodically. Mine doesn't have one like that.
I dont have any codes at the moment. Alright then i exclude that it may cause a problem!

It has nothing to do with why your engine won't rev.
Have you checked the ACS throttle body that is just past the MAF to see if it is fully open?

The translate of "charcoal canister" doesent give any results for me. Is it possible to explain what it is or some other name? vapor recovery system?
I havenīt checked the ACS yet, ill do it tomorrow and report results!
