Problem
I'm positive I have a vacuum leak I'll attach pictures for assistance. I'm going up upgrade to a cool air intake from K&N since the nipple on the air duct is cracked and the grommet fr the valve cover on the passenger side had to be replaced. I just want an opinion on if if anyone believes it's anything else as I'm about to change the fuel filter. When I push on the gas just barely while holding it steady it goes to 2000 rpm and drops back down to 1400. If I push harder constantly it will drop as the car moves faster mph wise. Eventually making a bogging sound while slowly accelerating around 1100 to 1200 rpm as if a transmission slip occurs. I think it's all due to the vacuum leak though so I'll work on that first. I've been using the same Issues others do as well as far as sometimes taking three attempts to start the car most times hence why I'm changing the fuel filter for good measure. Any help would be great I have a very decent amount of automotive experience and tools but this is my first camaro and 305 motor
is a video of me constantly holding steady pressure to the gas pedal and showing the way the RPM drops by itself without me letting up, Then at the end I press harder and you will see it slowly rise but slowely drop again
this hard silver line is cracked at the air duct going into the filter, may replace this with K&N since i can't find stock replacement without junkyard parts.
the grommet in the valve cover split in half so i pulled it out so it wont get stuck inside

any suggestions on where to start? a full mapping of possible areas? I've already stated the obvious one at the air line. I can't do anything about that one quite yet until I find a way to seal it or get a CAI, added video of the symptoms
