location

I can see the gas coming out where the rod meets the housing (where it slides through) on the passenger side. I turned the throttle cable by hand and when that rod rotates you can see air/gas come out on passenger side.

What brought it to my attention is I initially saw air bubbles going up through gas filter under hood. I heard the noise of water hitting a hot surface so I pulled the air filter. You could see it seeping from that same spot and hissing/sizzling as it hit the hot intake.
