Thanks guys. So if u were me, what would be your next step. Should I run a compression test or look to change the catalytic converter. Basically I'm asking what do I do to confidently determine the problem Instead of guessing.

I'd check compression before replacing anything. If a cylinder (most likely #5) has low compression, you're probably gonna be tearing the motor apart like I did

Compression is 155-160 and the fuel delivery isnt good. Only getting about 9 MPG. I was told that it could be a loose or bad lifter or spring next???
