    i dont recall what p0300 is but i know that seafoam can kick up a ton of carbon, especially if its been a long time since using it or your first time. that stuff can cake up on the spark plugs and bridge the plug. switch out your plugs and you should be fine. not very common, but not unheard of.

        Yeah I decided to change my plugs anyway but I noticed an oil spot under my car. My car has never leaked oil before and now after seafoaming it there's oil under my car. When I was changing the plugs I noticed oil on the passenger side of the engine. I'm not sure if its coming from where under the head. But take a better look tomorrow when there's sunlight out.

          someone correct me if im wrong but i would think the seafoam got rid of some "gunk" that help the oil leaks in place and now that its gone.........i might be wrong but yea the misfire is the plugs that are fouled

          edit: this was my 300th post, just a lil fyi :)

              Yeah I got a better look at it today and the oil seems to be coming from the rear of the passenger side head gasket.
