P0300, P0325, P0330 Error codes...need help...

[Reaper007]

Hi everyone I need some of your expertise. I own a 99 Q45t, Ive had it for a year. Recently I got a check engine light and the codes that popped up were P0300 P0325 and P0330. My questions are the following:

Is it possible that the misfire caused the knock senors to give a bad reading, or made them malfunction?

Or are the bad knock sensors the cause of the P0300 misfire code?

Which gaskets will I need for the job?

Does anyone have a service manual or guide that may help me with this repair?

I Appreciate you takin the time to read this and for any help you can offer.

Thank you,Jon
