A friend of mine phoned me earlier and said she is getting problems with her ka. She described the problem as this - when she is travelling at speed (over 25mph) and engages the clutch the revs raise rather than lower as they should.

any ideas?

 

idle speed control valve?

 

Dissconect the wiring plug to the speed sensor (between the speedo cable & gearbox) if the probs gone relace sensor.
