Are you getting funny exhaust?

The exhaust looks prety normal to me , I do have a crack in my exhaust manifold but I dont thonk that had anything to do with it

Sounds like the timing could be off... i.e. the timing belt could have jumped a tooth. When was the last time the timing belt was changed? May be worth pulling the covers off and making sure everything lines up. If it's off, it will have symptoms you're describing.

I just set the timing that was my first guess i also compression tested,fuel pressure tested,spark tested, set valve clearance, replaced and gapped spark plugs, tested fuel injectors on my homemade injector tester and measured resistence across them, and it passed every test i have a crack in my exhaust manifold right before my 02 sensor but it ran right before with it cracked is it possible that it got worse a caused misfire
