Hi. First I will say it is common for the ignition coil to go bad on that model windstar. When was the last time you had the spark plugs and wires and fuel filter replaced?

Customer: replied 2 years ago.
The fuel filter ,spark plugs and wiring were changed less than a year ago. The oxygen sensors were changed a week ago due to piston noise going up hill or really flooring the vehicle. I overheard the mechanic ask his partner if the computer had been reset .answer was no.How does that affect performance ? On Sunday I went to another place and had a diagnostic test done and it came out with the following codes 1000 -0161 -0171 - 0174 . I saw the answer that you gave someone about the 0171- 0174 results . Did Ford do a recall because of this ?

Hi .I wrote yesterday. Anyone home?
Expert:  EricFromCT replied 2 years ago.
Hi. I am here. P0171 and P0174 indicate that you have a vacuum leak. On some windstars people forget to reconnect a small plastic hose into the back of the air cleaner housing. If that is off it will set those codes. Also ford does not have a recall but there are some service bulletins on the intake gaskets leaking and there are updated bolts. Intake gaskets leaking or will set 171 and 174.
