I have a 96 Taurus with a V6 Vulcan engine and auto trans. After it warms up, the car will "stumble" at idle. This is more than just a miss. The engine rpms will drop about 100 momentarily (800>700). I can hear a "clinking/clunking" noise when it does this. It seems to drive/accelerate/cruise ok.
Any ideas?
