It says you removed intake res. in the 1997 Contour. The factory had a tsb (technical service bulletin on moosing). My sister's V6 1995 Mystique had the moose, it would moan loud and stall the engine. The dealer put in a kit of tubes and hoses, which I think would have been stock in the 1997 Tour, maybe try putting back the factory junk as a test.
