Hi all.

Ok. Using what I had on hand (measured to ensure this LED drew low
milliamps, though this was @ 12V).....

12V LED, + lead to TVS + ,  LED goes on, throttle at rest, throttle valve
switch closed, and goes off, throttle opened TVS open. Most importantly,
for my purposes, LED indicates that TVS is closed even when engine is
surging, foot off gas pedal. But....

What is that whistle sound at ~ 39" - 55" ?  Vacuum leak?

TB gasket is new, rubber hoses at EVAP hoses, FPR, PVC "T", all good. Air
distributor has no holes. Immediately noticed whistle while driving with
engine lid off. Did not hear it revving engine in driveway, lid off.

Red LED is mid screen at full screen view.
