Think I found the issue. I pulled the plugs and 1-3 were very good and firing perfectly but 4 was another story. It was very dingy, and didn't seem to be firing constantly. The plug wire itself was broken at the plug itself, and the plugs were also gapped larger. Specs show .034", and they were over .040". I didn't have a wire feeler gauge when I installed them but it was running well. The bigger issue was the bad plug wire. I found out at 8:55pm est and parts stores closed at 9pm est.
I will get a new set of plug wires, and keep the other three for spares in case something happens. I also have a new set of spark plugs on standby, and will also have the ignition module tested as well, just to be safe.
