Lexus LFA Mixture Preparation Error

My 2010 Lexus LFA with a gasoline engine has developed a mixture preparation error at 121364 km. Symptoms include reduced power, check engine light, rough running, jerking on acceleration, and occasional stalling at idle. Could a defective injector be the cause?

I had similar symptoms on my LFA. Did you check the throttle body? It might be related to the air-fuel ratio.

Thank you for your reply. Can you elaborate on your experience? Was the check engine light also on?

Yes, the check engine light was on as well. Eventually, I took it to a workshop, and they confirmed it was a fuel injection issue. Getting it checked professionally might be the best course of action.

I appreciate the advice. I had the injectors checked, and indeed, one was defective. Repair cost came to 515€. The problem is now resolved. Thanks again.
