identification of mystery engine part needed (1 Viewer)

[Lars]

It's a '93. Sorry I dont have a factory manual at this point so I have no clue what this item is.

With the hood up, I can manually rev the engine and hear a vacuum sort of noise from this part as I reach higher rpms.

It's a PAIR valve (pulsed air injection reed).

A little info on it.

I thought that was my flux capacitor. Oh well. I'll keep looking.
