I have done a motor swap from a 1999 to a 1997 eclipse 2.0 and the heater hose messed up, started leaking antifreeze and over heated but not bad an not for long before I pulled off.

I got the hose fixed but the car is still sputtering and last time I took the car out it had like 2 or 3 loud pops under it then it started sputtering and died in the road. Got it started back but kept sputtering until I turned it off.

Note when I turn the A/C on after a little bit it also made the car turn off and the oil light come on.

A guess based on the information could be one tooth off on mechanical timing. It will run but poorly.

See if you can get that video reposted and check your timing marks if that sounds like the issue.

I've came down to it that it's the purge valve but I can't seem to find it on the 420a

Why do you assume it's the valve? It's definitely not the valve itself. Maybe a vacuum leak in the system though. It's an easy check. Just remove the vacuum line and cap off the fitting. I circled it for you.
