Question

How do I fix the engine code P0300, misfire code in a 2008 Infiniti G35s 3.5L?

Answer 1

Hi there,

The multiple misfire code rarely has a simple solution. It can be an issue with an intake manifold gasket, timing chain, low fuel pressure, bad mass air flow sensor to start with. These all have to be checked to determine what is actually causing the misfire. Many times you will eventually get codes that are specific to the cylinders that are misfiring.
