Hi, my daughter's fiesta mk 4 1100 with automatic mixture and tickover with vatious sensors around will not settle to a low tickover.Take your foot off the throttle and the car keeps going.I checked vacuum pipes for leaks, but am fogged.I have voltmeters can I check and ajust anything to get the revs down, thanks.

hi Paul,
thanks for that sugestion, but the cable returns fine.I have found so far that after changing the complete carburettor the problem was still there, that is the engine still reved high for about 8 seconds and slowly dropped to 900rpm tickover.Makes driving very difficult having to over brake all the time.I have had some success in disconnecting the map unit and plugging sealing the manifold.The car appears to run normally now, but I will have to check the map unit now, thanks Duncan.

have you tried adjusting the throttle cable so its not so tight ?
