Hmm...mine just started doing this about a week ago. Right when it started getting cold out. It only does it at start up and until warm. My '99 SVT has just over 45,000 miles and it has NEVER done this before. I wonder what caused it to start? I thought 99+ Tours were supposed to be cured of this problem. When I'm backing out of my space upon startup it will moose just as I turn the steering wheel. After about 1 minute it won't do it unless I'm sitting at idle and I turn on the defrost/AC. If I turn on defrost it will moose and the idle will surge for about 5 seconds, will stable but moose will persist until I turn of the defrost. After about 5 minutes of driving it won't do it at all. Strange.
