P0300 Random Misfire

So my G is misfiring. But its not like a cyclinder misfire. Because all my spark plugs and coil packs are new and good. My question is what else can cause my G to misfire? Air leaks somewhere? Maybe replace some gaskets? I really dont want to take it to a mechanic so i could save money. But if i cant find the answer then that will be my last resort. Anyone have this problem?

Vacuum leaks, bad petrol. Are you sure your coil packs are connected in the right order?

I have the same code but I have oil leaking in my spark plug it will spit and sputter I'll rev it 2 times an than goes away but when driving to can feel it jerk sometimes but it hasn't affected my porformance when I stomp the throttle it still runs good an beats all these little honda ricer **** boys around here

Also I have replaced all spark plugs an the coil pack that I had oil leak into
