Question

I have a 1998 Ford four-wheel-drive that has a trouble code of PO 171

Answer 1

P0171 fuel trim lean bank 1

This is the condition of the engine. On Ford vaccum  are the most common cause for this code. There so brittle and break everywhere, so the price varies on what the cost is. If can just be one simple vacuum line. or the PCV hose getting collapse or ruptured. The cost would be one hour of a shop time and should not go any farther than that.
