Fiesta - Revs

[Mikey_W]

Hi,

My sister has an s reg (98) Fiesta i think it is a 1.1
When she changes gear or slows down at a junction the revs seem to stay the same or even increase. Does anyone have any ideas?

I know i haven't explained it very well, but it is like the throttle cable is sticking??

Thanks in advance

Mike
