Could you tell me the specific diagnostic code you encountered and what you did to fix it? Any information would be greatly appreciated.

I don't remember the exact code, but the problem stemmed from the chip tuning. I had to visit a workshop to have it properly diagnosed and addressed. I recommend you do the same.

I took it to a trusted workshop. Diagnostics confirmed the issue was related to the chip tuning. The car computer was reset and re-calibrated. The repair cost was 180€. The issue is now resolved.

I also own a Pathfinder, though it's a different year. I had similar symptoms once: reduced power and an error code. Did you use a scan tool to read the diagnostic code from the car computer? That's where I would start.
