What are you using to adjust the tick over speed? Are you adjusting the stop on the accelarator lever? Is it a Bosch pump or a Lucas? Do you have a waxstat cold idle device or a vacuum thingumy?

Hi Kowalski
Im adjusting the stop on the accelarator lever its a bosch pump with a waxstat cold idle device.

Can you tell whether the waxstat cable is slack or not? If the waxstat cable is slack, thats the cold idle setting, tight its hot idle (i.e. lower speed). I'm not exactly sure how it works internally, you could have a play with that cable.

hi agian jeremy
well the part im adjusting is on the rear of the accelarator lever there,s a little adjusting screw with a locknut and the screw goes up agianst a little round plastic thing with a spring i think ive adjusted the wrong part so ill have to reset it to where it was the accelarator cable is a little slack.

I don't thinbk I've posted on this thread before!
I'm not very familiar with the Bosch pump and can't help here.

hi agian jeremy
it appear,s ive givin you the wrong info futher looking more into this it has got a vacuuum thing on of the fast idle cable the other end goes into the pump wich has the fast idle screw what ive done is to adjust the fast idle screw now it idles at roughly 950 rpm that is the slowest i can get i also noticed a box on the rear left of the bulkhead with vacuum pipe.s going to it one is going to the rear of the vacuum device well one of the small pipe,s is squashed were it bends so i think this could have a lot to do with this prob what do you think guys.

I have changed 3 of the blue solenoids on my 2 Xantia TD's they don't last a long time, About £30 from the dealer, In normal driving they operate a lot so I think they just burn out or something
Follow the pipe from the vacumn thing to the bulkhead

thanks paranoid
yes the pipe goes to what looks like a aluminum box on the bulkhead that has got other pipes running from it one of them a plastic one has collapsed ill have to replace that one could possibly be part of the problem what do you think

Pipes go to 2 solenoids, one (blue) for cold running/ startup the other(green) to increase revs when the air/cons on, they are both pop rivetted on, 99.9% thats the problem, it has been on my 2 was messing about for ages with settings etc, it was that all along.
When its working correctly you will understand why the cable looks slack etc

I've had to replace the electrovalve that controls the idle speed on my '97 Xantia, it was a while ago, it seems to be a fairly common failure part and expensive for what it is.

thanks Kowalski
Were is the electrovalve and what does it look like. sounds like you have the same model as me mine,s an sx 1.9 td 97 has yours got aircon. Paranoid just out of interest were are the 2 solenoids as i think my car could be different to yours.

At the back of the lhm tank,under one of the nuts there is a metal bracket they are rivetted to this, its easy to see once the large rubber intake pipe is moved across (2 jubilee clips)
Access isn't to bad once the view is clear, only takes about 15 minutes to do the whole job, replace rivets with self tapers etc
