My 2010 Nismo threw this code and after clearing it would come back after a few miles. There was an actual misfire as well but nothing that could be isolated.

Multiple Cylinder Misfire P0300
My 2010 Nismo threw this code and after clearing it would come back after a few miles. There was an actual misfire as well but nothing that could be isolated. Turned out a rat had made a little home in the plenum under the intake and had chewed on the fuel injector harness. Little bastard chewed through some wires right at the soft bend on the drivers side of the engine. Very well concealed. Replaced the harness, cleared the code and haven’t had an electrical issue since. Car is parked currently with the dreaded CSC failure. CMAK & SB stage 3 & we’ll be fine.
