Trouble Shooting : P0300
Nissan

Probable Cause: ignition system fault, fuel system fault, large vacuum leak, MAF sensor fault, AF/H02S(Air Fuel/Heated oxygen sensor) sensor fault


Can any of these things possibly cause my car to shut down?

i would start with basics. fuel pressure and spark tests.

300 is most of the times related to tune up parts.
