My Ford Mondeo 18TD R reg has recently started to rev very high (4000+) after idling for more than 30 secs.
It happens as I am about to pull away before I release the clutch no matter how much I push own on the accelerator even if I just lightly touch.
I suspect it is a faulty or bad connection on a sensor but don't know which one.
I am reluctant to take it into a garge until I have some idea what the problem is and how much it is likely to cost.
Any ideas/help would be appreciated.
Thanks
Paul Carpenter
