when i press the clutch a get an excessive amount of revving on my ford ka 1999. when i have looked at the engine if i open the throttle cable their is a sucking noise from the pipe from the manifold to then servo unit. could this give me the high revs. the problem is not all the time.
The fault is due to a poor connection at the throttle position sensor connector. A later level connector needs to be fitted.
Suggest your dealer does the the repair as it is easy to get wrong
