Got a little impatient cause I was getting tired of not finding the problem so instead of doing one thing at a time to see if it fixed the issue I just swapped the fuel injectors and Idle Air Control Valve (idle has just been off since I bought this car) off my spare motor onto this car and put new spark plugs in. So far haven't had the issue anymore, knock on wood.

Noticed a fuel leak around the injectors so I changed the o-rings. Leak stopped and the engine stuttering has improved but not stopped. I am going to swap the injectors next to see if that is the issue.

Replaced O2 Sensor (car had a cloud of gas smell around it the entire time I've driven it, this fixed the issue)

Car also started having weird stuttering issues under load. Removed cat to see if better air flow would help, but this did not help.
