Default Flashing CEL With Heavy Load

Okay guys need some help here;

So my car was running $hit with a rough idle and it threw up the P0300 code along with the P0303. So what I did was remove the ignition coil and switched it to the #2 cylinder and long behold the code transfered. So I went and got a new ignition coil popped it in and it was idling perfect and I thought the problem was fixed until...

I put a heavy load on it (pedal on the floor) to make sure everything was good and lord behold it started flashing the CEL and a P0300 code. So I am now confused as to what it could be as all the spark plugs were changed that ignition coil was fixed. The battery is in top condition. I inspected all the vacuum lines for no leaks. The only thing left I could think of is the Camshaft sensor as it was throwing up a P0390 code but it went away. So I ordered a new part and I'm going to replace the BANK 2 exhaust side.

Please thou if anyone has input let me know what you think!
