Teana cylinder misfire

My 2007 Nissan Teana with a gasoline engine has 237508 km. I'm getting combustion misfires: rough running, check engine light, jerking when accelerating, and less power. Could it be the fuel pump or spark plugs?

The 2007 Nissan Teana experienced combustion misfires, indicated by rough running, a check engine light, jerking during acceleration, and reduced power. The initial suspicion was on the fuel pump or spark plugs, but further discussion suggested checking the fuel injectors. A professional diagnostic confirmed a defective fuel injector, which was then replaced to resolve the issue.

I had similar symptoms in my Teana. Have you checked the fuel injectors? A cylinder misfire can often be a faulty injector. Any changes in fuel consumption?

Thanks. How did you know it was the injector? Did you do any tests?

I suspected it because of the rough idle. My mechanic ran a test that confirmed it. I'd get yours checked by a professional.

It was a defective fuel injector. The repair, including diagnostics and replacement, was 515€. Thanks for the help.
