Hi Scotty,
I have a 2012 Nissan Sentra, 4D Sedan, Automatic transmission, 120k miles. Replaced all 4 spark plugs and 4 ignition coils with OEM parts. Dealer did a compression test on all 4 cylinders and no issues. They replaced fuel injector on cylinder 4, saying that was the issue. The car runs great.
The P304 code keeps pppping up after every few days. Car runs great but will not pass Smog in CA. Cannot remove the permanent code. Any tips would be appreciated.
