I need help finding a hose
I’m finally in the cusp of fixing my car to stop the misfires. But there is a tear in my vacuum hose which while small has caused some slight hesitance with my accelerating. But nothing terrible. I do also have a dip in idling if I’m driving a lot that day. I can’t find the hose anywhere online can anyone help me

Only hoses that would cause an issue like that are the PCV hoses, one from each head to the air intake box, and one from the PCV valve to the throttle body. I would recommend you replace the PCV valve as well. Should be near the back passenger side of the engine on top.
As for the misfire, check the connections on the coil pack for corrosion and replace the plugs and the wires as well. If that doesn't fix it, then you probably have a compression issue.

Is it not my brake booster hose I feel like that’s the issue

Do your brakes feel overly hard or squishy? That hose doesn't look bad, the PCV hoses crack from engine heat and leak, which will cause idle issues. A vacuum leak won't cause a misfire.

Looks like the booster hose is what you’re looking for. Looks torn right near the clamp. You could cut the ripped section off and should still be long enough to work and save a few bucks.
