S80 Lean Running Jerking

I've got a 2000 Volvo S80, diesel engine, with around 139k kilometers. Lately, it's been running really lean. I'm getting reduced engine power, the check engine light is on, and the engine runs rough. It also jerks when I accelerate. I'm thinking it could be the fuel injectors, any thoughts?

A 2000 Volvo S80 with a diesel engine is experiencing lean running, reduced engine power, a check engine light, rough running, and jerking during acceleration. The initial suspicion is on the fuel injectors. A similar issue was resolved by addressing the injection valve/injector, which restored the vehicle's performance. It is suggested to have the air-fuel ratio checked and possibly visit a workshop for a thorough diagnosis.

Did this summary help you solve your problem?

I had a similar lean running issue with my S80. Has the air-fuel ratio been looked at? When my check engine light came on, the spark plugs were blamed. Maybe check the state of your intake manifold?

Spark plugs on a diesel? I'm skeptical. Air-fuel ratio, yeah I thought about that, I might need to find someone with the right equipment to make the measurements. I was hoping to maybe avoid that for now. What exactly was it with your S80?

Okay, spark plugs are not the culprit in your case, excuse my ignorance. I wasn't thinking. If the air-fuel ratio is not optimal I would just recommend going to the workshop.

Thanks for the input. Seems like getting it checked out is the best bet. It was the injection valve/injector. Cost me 515€ to fix it, but runs like new now.
