Customer Question

p0171 code is registered from autozone code scanner. just changed out maf sensor, heard a knock and then the check engine light came on. rough idle at rest, almost stalls and then revs slightly higher than normal now.....thinking an o2 sensor is the culprit
JA: Does the light stay on, or does it blink?
Customer: stays on
JA: What is the model/year of your Nissan?
Customer: 2012 sv
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: yes i am. like i said before. just replaced maf sensor and then the check engine like came on. it was driving poorly and i believe there was a leak in the aftermarket intake. i believe i fixed the leak, but i still feel the o2 sensor is causing the issues.
JA: Anything else you want the mechanic to know before I connect you?
Customer: i think thats it
