Skoda Kamiq running rich
Summary of the thread
A 2019 Skoda Kamiq with a gasoline engine is experiencing issues of running rich, leading to reduced engine power, a check engine light, rough idle, excessive fuel consumption, and jerking during acceleration. The suspected cause is faulty fuel injectors. After diagnostics at a workshop, the issue was confirmed to be the fuel injectors, which were then replaced, resolving the problem.

Interesting. The oxygen sensor... wouldn't that throw a specific code? I thought a bad oxygen sensor would give a different reading than just 'running rich'. How did you diagnose it on your Peugeot?

Yeah, it did throw a code, but initially, it was intermittent and kinda vague. The garage guys checked the air-fuel ratio and saw it was consistently off. Given your mileage and symptoms, plus the rich mixture, the injectors are a strong possibility, but without proper diagnostics, you're just guessing. It's best to get it properly diagnosed at a workshop.

You were spot on. I took it to the shop, and after diagnostics, they confirmed it: faulty fuel injectors. I had them replaced, and now she's running like new. Cost me 515€, but it was totally worth it. Thanks for the insight.

Sounds like a rich mixture issue. I had similar symptoms – reduced power, rough running, check engine light – with my old Peugeot. Turned out to be a faulty oxygen sensor messing with the air-fuel ratio. Have you checked that?
