Hey,
I just replaced my starter last week and the check engine light came on this week. I've got three codes coming up:
P0171 -System too Lean (Bank 1)
P0174 -System too Lean (Bank 2).
C1234
Where should I start for the leans?
1. Vacuum leaks
2. Restricted fuel filter or bent/pinched fuel system lines
3. Incorrect input from other sensors, such as the Mass Air Flow Sensor, which may not always drop a separate code
4. Engine misfire
5. Bad O2 sensor
Thank you.
