Couple days ago my CEL came on, felt a loss of power but slightly.. other then that the car seems perfect. Had the car scanned for codes and got 3 codes back which are P0171B,P0174B,P2097. Simple breakdown is that my car is running too rich and too lean at the same time?? How is that possible? Has anyone had a similar issue, what could be the main problem parts wise? Thanks guys!!

 

First thought is the O2 sensor is faulty.

 

Thats possible, Update: At random times the car will stutter/buck during acceleration..

 

First thought is a vacuum leak..."bucking" is probably limp mode.
