My '97 SE used to have the resonator setup like they show here:
http://contour.org/FAQ/tsb/img/TSB-96-19-5.jpg . At some point I seem to have over-tightened one of the hose clamps on the resonator, because one end of it was crushed and leaking air through the crease. I took the resonator and hose out, and replaced it with a short piece of conduit and a heater hose. It seems to function OK, but the car now mooses fiercely once in a while and I know it's going to be aweful when the weather cools off (I've been wrestling the moose for a few years now, was running a restrictor with decent success).
If I understand correctly, at some point subsequent to the 1997 model year Ford changed the idle air control assembly, dropping the resonator and replacing the IAC valve with a slightly different model. I am currently thinking of replacing the IAC valve with a new one for a 2000 Contour. NAPA lists different part numbers for 1997 vs 2000. Should I expect this to fit, and stop the moose problem?
Ford refers to moosing as "hooting", which doesn't seem very accurate to me but might help you imagine the sound. It helps to read it "mooooooooooooooooose"; then the similarity is more clear. I do know that if it does it when I come to stop at a crosswalk, it really scares the pedestrians. It sounds like the horn on my Triumph, only louder.
