Lean bank 2
I have a 2000 exp with the 4.6. It is running rough and showing code for lean bank 2. Can someone give me an idea about what would cause this code. Ford dealer wold not help they just wanted me to pay to run diagnostics. I just cant afford that right now,but I would really like to have me truck runnig again. If you could help me it would be great. Thanks for looking.
