Is this engine coolant on my spark plugs? P0300

I don’t know, honestly, just a hunch. Partially also wishful thinking since I’m confident I could replace them myself lol.

It’s weird because the car ran like a peach on the drive back from Z1, a 5 hour drive. Keep in mind Z1 also extracted a crap ton of power out of this car for the mods installed. It didn’t start acting up until I left for work the first cool morning. I also filled up with gas the day before it started acting up. On my next fill up I intend to go to a different station and I was thinking of adding a bottle of the Chevron fuel system cleaner BS. Just to rule out bad gas.

I’m just anxious to get it fixed, it bums me out hard as hell when my car isn’t running right. This is why I’m tempted to just start throwing parts at it lol. I’m not going to, but it’s tempting.
