Lexus NX Reduced Engine Power

That sounds frustrating. I had a similar issue with my 2014 Opel Insignia. Reduced power and the check engine light were on. In my case, it turned out to be related to the air flow and air intake. I was getting a response delay when accelerating. Have you checked for any unusual engine idling or tried cleaning the throttle body?

Thanks for the quick response! I haven't checked the engine idling specifically, but I will now. When you say air flow, did you notice anything in particular? And how did you end up fixing it?

Yeah, with the Opel the airflow sensor was faulty, causing the engine to misinterpret how much air was coming in. That messed with the fuel mixture and caused all sorts of problems. I ended up having to get it replaced. Honestly, it's probably best to take it to a workshop to get a proper diagnosis.

Thanks a lot! I appreciate the insight. Took it to a workshop and you were right. Defective throttle valve and they are estimating around 265€ for the replacement. Thanks again for the help!
