Kuga Hybrid Rich Running Defective Injector

My 2020 Ford Kuga Hybrid is running excessively rich at 162203 km. Reduced engine power, check engine light, rough running, higher fuel consumption, and jerking on acceleration. Could it be a defective injector?

I had a similar issue with my 2018 Opel Insignia. Nearly identical symptoms. Have you checked the air filter and spark plugs? A clogged air filter or fouled plugs can cause a rich mixture.

Thanks. Were there any diagnostic trouble codes (DTCs)? Did replacing those parts fix the issue in your Opel Insignia?

Yes, there were DTCs for a rich mixture. Replacing those parts only helped temporarily. The real problem was a faulty injector over-fueling the engine. I'd suggest a good workshop.

Took the Kuga to a workshop. They confirmed a defective injector. Replacement fixed it. Total cost: 515€. Thanks for the help.
