Hello. New member question.
I have a 2004 Ranger 2.3. The check engine light came on. I had Murrays Auto Parts check the code, and it came up PO171. They told me that it is one of the oxygen sensors, and the description is lean bank 1, and the Haynes manual says the trouble code is Fuel System at adaptive limits bank #1.
The truck seems to run fine. Can anyone help me decipher this?
Thanks in advance for any help or suggestions.
