XM idle control box?

Post by ekaftan »

A friend has a 1994 2.0 manual transmission XM that stalls at traffic lights. Local mechanic is asking for US$500 to replace the 'antistall control box' that he claims is under the dashboard.

Is there such a thing?

thanks.

New one to me...there's an idle control valve (fitted onto the throttle body) which is probably the first port of call. About £80 new in the UK (or it was on my ZX 1.8i - very similar engine).
On mine it's right on the top of the throttle body. They can sometimes be recovered by removing and cleaning out with carburettor cleaner; sometimes the whole throttle body needs cleaning out.

For $500, i'll come out there and do it myself!

There is a considerable amount of information for download on the Citroen y site - and the BX and Xantia info seems to be in English. You may be able to download a manual for it which may help.

Also some XM pages on the Citroen DIY site

While you are there the technical guide referred to (again downloadable) is well worth reading on Citroens in general and deals with the various types of XM suspension etc.

Hi - try looking at this:

As Phil said it's the most likely culprit. When my Xm used to have a similar
problem, it used to run properly again when it got a good firm clout from a
screwdriver handle..

Eventually got fed up and changed it and never had the problem back!

Effectively it's like a Stromberg carb single needle "jet" that can stick preventing
the air into the inlet circuit. If it's present on the car in question it'll be
found near the battery box!
