Navara combustion issues

Hi, I'm having a problem with my 2004 Nissan Navara (gasoline engine). It's done 74286 km. I think there's something wrong with the combustion. I've noticed a distinct loss of power, the car jerks when I accelerate, and there's some smoke coming out when I put my foot down. Also, I checked and there's an error code stored in the memory. Any ideas what could be causing this?

A 2004 Nissan Navara with 74,286 km is experiencing combustion issues, characterized by a loss of power, jerking during acceleration, and smoke emissions. Potential causes include engine knock, carbon deposits in the combustion chamber, or issues with the knock sensor and ignition timing. Solutions suggested include using higher octane fuel, checking the knock sensor, and cleaning the combustion chamber, which ultimately resolved the problem after professional intervention.

Hey, I had a similar issue with my Navara. Sounds like engine knock. Have you tried using a higher octane fuel? It might be worth checking the knock sensor and ignition timing too. Could also be carbon deposits in the cylinder heads.

Thanks for the reply! How did you fix yours? Did you manage to sort it out yourself, or did you have to take it to a mechanic?

I tried a few things myself, like higher octane fuel and cleaning the spark plugs, but nothing really fixed it permanently. Eventually, I took it to a workshop and they found heavy deposits in the combustion chamber. They cleaned everything and the problem went away.

Thanks. I appreciate the advice. I took it to a workshop and they confirmed deposits in the combustion chamber. They cleaned it all out, and it cost me about 425€, but it seems to have sorted the problem. Runs like a dream now!
