My Ford Focus Zetec 1.8 is suffering with high engine revs when I come to a stop, described in a Ford technical bulletin as 'throttle holdup'.

The age of my car is May 2000. This puts it in the age range covered by the bulletin. Having tried many other suggestions, this is currently the most likely cause.

The bulletin gives a 'Finis' code for the manifold, which is 1111723, however all manifolds are marked with part numbers such as '988F9424KB, or similar.

Ford refuse to give me a part number, which makes searching for a second hand part very difficult. I've seen several different part numbers claiming to be suitable for my era of car, which just adds to the confusion.

So what I am asking is, could anyone who knows the part number that is Finis code number 1111723, please let me know.

Many thanks, Ross.
