Any major vacuum leaks? Possible intake? Have you checked fuel pump pressure?

No vacuum leak and fuel pressure is good

I really feel it has to do with an intake leak. Double check to make sure there are no trouble codes stored in the computer.

That is a knock sensor error. THe knock sensor can play with the ignition timing. Have you checked it?
