I have a small niggling issue with my car - it's a 2004 1.8 Mondeo. The issue is quite weird, so sorry if I don't explain it well. The scenario is thus. I'm cruising along at any speed, and slow down by braking or taking my foot off the accelerator. I've slowed down to my desired speed, and so put my foot back on the accelerator to carry on. Now, as soon as I press the accelerator, there is a slight jerk/clunk as I press the peddle. The best way to describe the jerk is as if something has engaged roughly, very similar to bringing the clutch up unsmoothly. I don't know if it's related or not, but I'm finding it very hard to drive the car smoothly. When changing gears and bringing the clutch up slowly, there is still a jerk. Any help would be great.
