Hello, I'm new to this forum and have a 1997 Contour GL 2.0 Zetec. I was wondering if anyone else has a large amount of knock around the higher rpms of each gear. I have tried upping my octance, but this does not help. Also, the car just seems too sluggish for a 2.0L. Maybe I am just expecting too much out of my car, but the power seems cut down significantly to what I think a 125hp 2.0L could do. Any input would be appreciated. Thanks, hope to be on here more in the future. Oh, and no dyno or anything here, so I can't give you any numbers.
