Qashqai fuel injector problem

My 2023 Nissan Qashqai hybrid is guzzling fuel. Only done 222794 km! The check engine light is on, it's running rough, and feels like it's lost power, especially when accelerating. Getting some serious jerking too. I suspect it's running way too rich. Any ideas before I lose it completely?

A faulty fuel injector was identified as the problem, leading to excessive fuel entering the cylinder. The issue was resolved by replacing the defective injector, restoring the vehicle's performance.

That sounds frustrating! I had a similar issue with my Qashqai. Reduced engine power, rough running, and the check engine light were all happening to me. Have you checked for any obvious signs like a bad air filter or any leaks around the intake manifold? It could be messing with your air-fuel ratio.

Thanks for the quick reply! I've checked the air filter – looks okay. No visible leaks around the intake manifold that I can see. What exactly was the problem with yours? And how did you figure it out?

In my case, it turned out to be a faulty fuel injector. It was dumping too much fuel into the cylinder, causing the rich condition. Think of it like a leaky tap - constantly dripping when it should be a controlled spray. That's probably beyond a DIY fix, as it could impact the catalytic converter and oxygen sensor readings. I'd recommend getting it checked by a workshop, might save you some headaches.

Thanks so much for the advice! Took it to the shop, and you were spot on – defective injector! Cost me 515€ to get it sorted. Runs like a dream now. Really appreciate the help!
