P0300 Misfire

Had P1147 & changed the O2. No longer have the P1147 but now have P0300 misfire. Did no do an ecu reset when I changed the sensor. Any ideas?

i keep getting this code. i put the NWP intake spacers on and new spark plugs at the same time. my rear VC must be cracked a bit since there was oil on the spark plug, but i didnt have one so i need to change it soon

why does this keep coming on?

I had the same thing.. turned out I overtightened my I'M and cracked it causing an intake leak. Possibly u cracked it or missed a spot with your sealant?
