What do these codes mean for a 1995 Ford Windstar LX 3.8L; PO171 Bank 1 Lean, PO174 Bank 2 Lean, PO402 EGR Flow, PO732 Incorrect Ratio 2nd, and PO733 Incorrect Ratio 3rd? I already replaced the Neutral Safety Switch, fuel filter, transmission fluid, and filter. I want to know what parts I need to replace, where are located, and if the job need to be done by a mechanic.
