My 16 fusion been running great, bought it used.on my way home from work I was going about 75mph. Traffic hit so I allowed down and when it started to flow I slowly pushed gas pedal and at or right before 2000rpm car started to jerk. So I let of the pedal and it stopped. Car didn't turn off. So I pushed on it a little harder and it speed up like normal. It only does it when I slowly pushed the pedal when I'm hit 2000rpm. Any one please have any idea what it is??
