Pt.3 I also checked spark plugs on the passenger side and they all looked good but imma check the driver side tomorrow after work. But any ideas an what could cause this would help big time. Thanks

Pt.2 i had a P0300 come back and I put octane booster in my tank and ran it and it did fine and didnt have issues or anything and the P0305 never came back but when I went to fill up my gas tank with 93 gas it started random missfire "P0300" again but I put octane booster it started to run fine and I deleted the code again so I can pin point it more. Any info what could keep this coming back let me know please.
