The car is making a screeching noise on cold start only. As mentioned in many past threads, I suspect that it might be the AIR pump which is out of its way. M.B.DOC mentioned in one of the post that "There is a 2 pin electrical connector for the pump under the plastic cover at the front of the valve cover. Could be un-plugged 1 morning to test." (The post is right
here.) Can anybody give me more detail where to find the plug? Thanks
