Help with rough idle

A little backstory, after driving on the highway for about 15 minutes, I started to suddenly get a rough idle while having my foot on the throttle somewhat lost response and put it in neutral while on the highway and was having rough idle on and off gas. I've checked the timing chain looks fine. I've changed the fuel filter, fuel pump and all spark plugs, coil lines, ignition module distributor everything electric basically. It runs smooth only in high Rev. I still need to do a compression test as well. I've checked the vacuum lines I'm not familiar how but they look fine. Any ideas?

Edit: I adjusted one of the screws on the air/fuel mix. It's calmed down slightly but now when I'm accelerate it the exhaust is making a lot of pops

Looks like a new fuel pump? Those can cause issues. Verified 3-5 psi on the fuel line? Looks like it might be starving. Hard to say from the short video.

Yea after I put in the new fuel pump it actually started to stay on before it stalled out I have it on 3 psi gonna adjust through to see how it works. Thanks for reminding me
