Does anyone know if an IAC valve Part# 978F-9F715-AB will interchange with a Part# F8CE-9F715-AB valve. I have a bad IAC on my 2000 Contour and have found a new valve at a salvage yard for $40 compared to $160-$200 retail from Parts Stores. There is no physical difference in the two valves and I can save $120 if the "F8CE" will replace the "978F". Any thoughts or educated guesses out there?
THANKS
