Navara rough idle defective injection nozzle

Hey, hoping someone can point me in the right direction. I've got a 2008 Nissan Navara with a gasoline engine, mileage is sitting around 92k km. Lately, it's been acting up. Having major issues getting it started, and when it does finally turn over, the fuel consumption is noticeably higher. Power seems reduced, and the engine idles rough – sometimes it even stalls out completely. I'm thinking it might be the injection nozzles, maybe clogged? Anyone else had similar experiences?

Sounds rough. I had similar issues with my Navara, symptoms definitely ring a bell. Poor starting, rough idling... Did you notice any difference in emissions, maybe a stronger smell or anything like that? Could very well be the injection. Is the engine noticeably louder than it used to be?

Good shout on the emissions, hadn't really paid close attention there. I will check it tomorrow. But yes, it does sound louder than usual. So, if it was your injection nozzle, what was the fix?

Well, I tried fuel additives at first, but no dice. Symptoms kept coming back pretty fast. Ended up being a defective injection nozzle. I'd strongly suggest getting it checked out by a workshop. That's my 2 cents.

Appreciate the insights! Looks like I'll bite the bullet and take it to a workshop. I'll let you know what happens. In the end it was indeed a defective injection nozzle. Got them replaced and the problem vanished. Repair cost: 515€ Thanks again!
