Question

2002 Infiniti I35 with code P0021 and P0300. My car is missing and when I drive it then shows multiple cylinder misfires, I change bank 2 sensors and coils and spark plugs and still, I didn't get out of the problem my car is an I35 Infiniti 2002 model??

Answer 1

Hi there,

With this code and the multiple misfires, it would be a good idea to check the engine compression. If it jumped time on bank 2 it will cause the misfire codes and also the code for the IVT solenoid. I would check compression as a next step
