I have a problem that I have had for a while,and my dealer can't find out why, that I would like some answers too. My Tour is a 2000 SE with a Zetec/ATX 41,000 miles and I bought it with 29,000 it has a tendenacy to miss when ATX is shifting up or down under load. Does anyone have any ideas??? I have a new IPS installed and a TPS installed with a total induction cleaning. Again any ideas. I was going to put some new wires on it.
