 98 ford contour 4 cycl auto
Yes, It can happen in a 98, because it happened in mine.
I called some dealers up and i was able to get mine for around 50 dollars including shipping. It is easy to install and my car had the same symptons. It was bucking a lot, and sometimes it would be fine for 100 miles then start up again really bad! It had a mind of it's own. So yes, replace it if u must, but first take it off and try to clean it because it might have some degreaser or something down inside interferring with with the sensor. |
