Maxima Reduced Engine Power

Interesting. I drive a Nissan Maxima too and had similar symptoms not too long ago. Did you notice any delay in engine idling or air flow response?

Yes, the engine response does seem delayed, almost like it's in a limp mode. What was the ultimate cause in your case?

That matches my experience exactly. It turned out to be a defective accelerator pedal. My advice would be to go to a workshop to confirm the diagnosis.

Thanks for the insight! You were right, the workshop confirmed the accelerator pedal module was defective and replaced it. The all-in repair came to 265€. I really appreciate your help!
