My 2012 g37x has the check engine light coming on and the engine vibrating. My mechanic replaced the ignition coil, spark plugs and fuel injector, but the issue didn't go away.

I'm taking it to the dealers, but wanted to know if anyone has had this issue?

Gotta read the codes. No help can be offered without them.

what was the code that set the light? sounds like your guy just threw parts into it without knowing fully what is the root cause. ignition coils are pretty solid in nissan cars, usually the coil boots cause arcing when it has a crack or hole in it. fuel injectors rarely go bad, it does happen but in most vehicles fuel injectors are not a common part that just takes a dump.

The initial code was P0305, which is cylinder 5 misfiring. After replacing the ignition coil, spark plugs and fuel injector, that code went away and became P0300, which i understand is a general misfire code. He did some diagnostics today but came up empty, his next step is to get into the engine for an additional diagnostics. Any help is appreciated.
