Skoda Praktik Diesel Engine Running Lean

My 2010 Skoda Praktik diesel is giving me grief. The engine is running way too lean. I'm experiencing reduced engine power, the check engine light is on, the engine runs rough, and it jerks when I accelerate. I've checked the obvious stuff like the air filter. Could it be a defective injection valve or injector? Any ideas where to start?

The 2010 Skoda Praktik diesel engine was running lean, causing reduced power, a rough engine, and a check engine light. The initial suspicion was a defective injection valve or injector. After checking common issues like the air filter, it was suggested that faulty fuel injectors could be the cause. A visit to a mechanic confirmed the problem, and replacing the injectors resolved the issue, restoring normal engine function.

Reduced engine power and a check engine light on your Skoda Praktik? Sounds familiar. I had a similar issue with my Praktik. Have you checked the fuel injectors? Rough engine running and jerking were the exact symptoms I experienced when one of my injectors went bad.

Really? Faulty fuel injectors? I wouldn't have thought of that. Did you also experience the same loss of power and the check engine light? How did you figure out it was the injectors and not something else like a vacuum leak in the intake manifold?

Yes. Identical symptoms, including the check engine light. After eliminating other potential causes, the mechanic pinpointed the fuel injectors. Given your vehicle's mileage and the symptoms you describe, it's probable you're experiencing a similar malfunction. I suggest a visit to a qualified workshop for a diagnosis and, if necessary, replacement of the affected fuel injectors.

Just wanted to let you know, you were right! The shop confirmed it was a faulty fuel injector. Replaced all four, and the engine's running smoothly again. The air-fuel ratio is normal, and the check engine light is off. Cost me 515€, but it's worth it to have my car back in good shape. Thanks for your help!
