Wierd problem

  1. Hi all, Hopefully someone can shed some light on the weird issue I am having at the moment.

    When I let off the throttle either going down a hill or just coming to a stop slowly without breaking, it fills like I am touching the accelerator quickly and letting off. This means the car kinda speeds up or jumps forward only briefly but if im not expecting it, I can see myself going up someones ass soon.

    Any ideas?? I had a 6 year service recently but this didn't cure it.
     
  2. My 250 does this when it's cold, It's never done it when it's up to temp.
     
  3. Mine does it only when it's up to temp. Could it be a fuelling issues maybe? I'm just guessing I fix computers not cars lol
     
  4. Mine is "kangooroo" when cold. I was told on this forum and at Renault that it is trait of F4Rt.
