Lexus RC Engine Mixture Error

My 2017 Lexus RC with a gasoline engine is having issues. It has 157097 km. The engine has reduced power, the check engine light is on, it runs rough, jerks when accelerating, and sometimes stalls at idle. It seems like a mixture preparation error. Any ideas?

Whoa, sounds rough! I had a similar issue with my RC (although, thankfully, not all those symptoms at once). Check your injectors. From what you're describing, a faulty injector is likely your culprit.

Thanks! What symptoms did you have? Did you try any diagnostics before checking the fuel injectors?

Sure thing! Mine was mainly the rough idle and the check engine light. The workshop identified it straight away. My advice? Don't waste time and get the injectors checked. I bet that's it!

I took it to a workshop, and their diagnostics showed one of the injectors was defective, like you said. The repair cost 515€. Thanks for the help!
