these fiestas seem riddled with electrical problems. this has been the most unreliable car i have owned. i thought buying a fiesta was a fairly safe bet.

i checked the switch and all seems fine. the revs rise to just under 2k when the clutch is pressed or you put it in neutral then take ages to drop to idle. a speed sensor is going to be over £80 with vat so a little apprehensive on buying it if unsure will solve problem.
