Lexus CT200h Engine Jerking and Power Loss

Hi, I have a 2013 Lexus CT200h. It's got 108012 km on the clock. Recently, I've noticed reduced engine power and the check engine light is on. Also, the engine runs rough and it jerks when I accelerate. I suspect it might be running lean. Any ideas?

Hey, I had something similar happen on my CT200h. Check engine light and all. Did you notice any change in your fuel economy, or any weird smells? It could be a faulty oxygen sensor messing with the air-fuel ratio.

Thanks for the tip. I haven't noticed any weird smells or changes in fuel economy. Is the oxygen sensor difficult to change?

Nah, the O2 sensor isn't too bad to swap, but from what you're describing, and given the jerking, it honestly sounds more like a fuel injector issue. I'd get it checked by a workshop, could save you some headaches.

Okay, thanks for the advice. I took it to a workshop and you were right, it was a defective fuel injector. Repair cost me 515€. Runs great now!
