Nissan Patrol y60 td42

[nurikeshi1277]

Hello everyone. My name is Nurlan. I'm from Kyrgyz Republic, Central Asia. Got myself my first ever Nissan Patrol y60 td42 (no turbo). Yet I know not much about the engine and the vehicle itself. But I'm learning. I've discovered a problem yesterday. While riding, it felt like an engine was misfiring. Especially on 2 and 3 gear. Could it be a simple air leak? How can I identify it by myself? Help me, please!https://uploads.tapatalk-cdn.com/20250630/c5743430f657bcb3bcf0254b5db97a29.jpghttps://uploads.tapatalk-cdn.com/20250630/81ac50bca13c11b07b39fa4e01902858.jpg

Hello and welcome, Nurlan,

A misfiring diesel can only be fuel related.
Go over the fuel lines for leaks.
Check the pump and injectors aren't leaking or sucking air.
Best of luck, let us know how it goes.
