Toyota Noah Hybrid Stalling

My 2017 Toyota Noah hybrid (116264 km) has poor starting, higher fuel consumption, reduced engine power, uneven idling, and occasional engine stalls at idle. Could this be an injection nozzle issue? Has anyone else seen this?

I own a Noah, though not a 2017 model. Your symptoms sound like a problem I faced. Can you share any diagnostic steps you've taken? Have you checked the gasoline or emissions control components? Any OBD-II error codes?

I haven't used an OBD-II scanner yet, but that's next. The gasoline looks normal. Which emissions control components should I check? Did your issue also include engine stalling?

Engine stalling at idle was frustrating. Check the oxygen sensors and catalytic converter, though a dirty injection valve is likely. Fuel injection systems are complex, so consult a technician. A bad injector could cause more damage. Get a diagnostic evaluation at a workshop.

A professional diagnostic assessment is best. I'll book a workshop appointment. Thanks for sharing your experience. It seems I will have to prepare for a repair bill in the region of 515€. I will post the solution when it's resolved. Thanks again.
