Went to put the car away before and started it up there was a clunk when i pressed the accelerator pedal, now when it starts it revs to about 4k!!! dont want to start it again like this incase it does any damage ,being stone cold.When you sit in the car the cable moves under the bonnet so im guessing it hasnt snapped? altho if you lift the pedal rather than push it in it comes out of the locating point in the bulkhead.Should it do this.?
