today my 350z just started running like crap it was bogging out and the idle was all bouncing around than my check engine light came on i hooked up an obd 2 scanner and the codes P0300 which is random/multiple cylinder misfire and P0327 which is knock censor what do you think the cause of this could be and how can i fix it. Could it maby be my spark plugs?

 

Do you think maybe the knock sensor having a problem is causing the other problem?

 

idk i think the other problem is causing the knock sensor to set off

 

My thinking is that if the knock sensor is toast, then the bouncing and bogging would occur.
In the words of Chevy Chase, "Put a little butter on it". (that'll fix anything!)

 

haha thanks man so you think the knock sensor would cause the cylinder miss fire code because i had some guy today tell me that wouldnt cause the miss fire but he didnt seem like he really knew what he was talking about.

 

Ever figure this out having the same issue.

 

Misfires would make the knock sensor go off if it was missing really bad not vise versa. Usually u will see the knock sensor code by itself if it was going bad or sensed excessive detonation or pinging. How many miles are on it and have the plugs been changed?
