Hi all, brand new owner of an 01 spa yellow s2k.

a couple days after purchase i noticed a high pitched ringing come from the engine bay at idle. the noise becomes louder as rpms drop (engine stumble, etc)

upon initial inspection sound seems to be coming from the front of the engine, close to the intake manifold.

any ideas as to where i should start with my diag. the noise is hearable through the video linked.
