Maybe someone should check and see how prevalent this problem is. I believe I have a similar problem with my Contour (98 Sport-SE, 6cyl. 5speed) It "jerks" when i lightly step on the gas or let off the gas with a gear engaged. It is more noticeable with the a/c on and also seems more noticeable in 1st-3rd gear, although that may just be me. I didn't think of it as a major problem, but an annoyance. Perhaps I should rethink the situation. I'm not a big poster here and don't know anyone at the board, but some of you that do might want to ask around and see if anyone else has had this "minor" annoyance. My car is the first and only standard I have driven thus far and I attributed the jerking to something that I was doing wrong (I am also the only person that has actually gotten to drive my car any reasonable distance since I bought it.)
