Hello Scotty, i been having this p0330 random misfire issue with my 2010 370z Nismo for over a year now. I changed my spark plugs and did a 60,000 mile tuneup. I can’t tell you how many times i have gone to different mechanics and the outcome have been alll the same no body can find a problem with my car lol. Someone told it could be the flywheel rattling to much or the cam gear have gone out of alignment. Scotty i need your help!!!
