Armada Lean Fuel Mixture

My 2014 Nissan Armada with a gasoline engine is running way too lean at 157947 km. Engine power is reduced, the check engine light is on, and it's running rough. Plus, it's jerking when I accelerate. I'm guessing it's a fuel injector issue. Has anyone else experienced this?

A 2014 Nissan Armada is experiencing a lean fuel mixture, resulting in reduced engine power, a check engine light, rough running, and jerking during acceleration. The initial suspicion is a fuel injector issue. A similar case was resolved by replacing faulty fuel injectors, which improved performance. Checking the throttle body and spark plugs is also suggested as potential contributing factors to the lean air-fuel ratio.

Did this summary help you solve your problem?

Sounds familiar! I had similar symptoms on my Armada. Did you check your spark plugs and throttle body? Could be contributing to a lean air-fuel ratio. Is it misfiring?

Thanks for the quick reply! Spark plugs are relatively new, but I haven't touched the throttle body. When your Armada was doing this, did you notice it more at certain speeds or under specific load conditions?

Yeah, mine was the worst when accelerating uphill. Eventually, I took it to a shop. Turned out a couple of fuel injectors were shot. Cost me a pretty penny but solved the problem immediately. Better get it checked out.

Appreciate the insight! That confirms my suspicions. Looks like I'll be booking it into the workshop to get the fuel injectors replaced. I was quoted 515€ for the job, which seems reasonable. Cheers!
