no i dont have it
Porsche Mechanic: Jake, Automotive Technician replied 11 months ago
Thanks, ***** ***** engine seem to running rich or bogging?The reason I was most interested in fuel trims readings, is the majority of power loss related issues can be traced back to fuel trims. Those readings and corrections are the easiest way to diagnose what's causing them (I.e MAF, air leak, etc)With no codes and no fuel trims it can be pretty tricky.Does it seem to be more noticeable at high or low RPMS?

at acceleration
Customer reply replied 11 months ago
could it be the 02 sensor?
Porsche Mechanic: Jake, Automotive Technician replied 11 months ago
Thanks, ***** ***** assumed. Most power loss issues feel like a bogging as you increase load, usually due improper air/fuel metering at the MAF. The A/F o2 sensor (upstream) can cause similar issues as well.

Porsche Mechanic: Jake, Automotive Technician replied 11 months ago
