ok, I couldnt find any leek. But maybe Malcolm, you or someone else can help identify what this thing does. My uncle was helping me and neither of us knew, not that I know anything anyway.

It was making a ticking noise as the engine was running.

Charcoal canister vent (purge) valve.
Part of the fuel fumes anti-pollution system on your Xantia.

If you ever get to dismantle driver's side frontwing, you will find that the screen washer reservoir and charcoal canister are located in there.

The valve hose at electric plug would end up in the throtte housing or somewhere else in the intake air ducting. The opposite hose is connected to the charcoal canister. The valve in turn is controlled by the engine ECU which opens the valve under certain engine conditions - but NOT during idle :!:

Thanks for the link. So you think it could be the hose to the map sensor?

The problem with the car wasnt enough for me to worry about I thought, especially over the chrstmas period, but today, I went out and was driving along fine and 'chug chug' the car starts going funny. I'm going about 50mph and am slowing down, I notice the revs are at 0. It doesnt matter if I press the accellerator or not, it just wont rev above 2000rpm and if I dont press the accellerator it idles around 2000 as well.

So I come to a jurky halt on the main road, and am pressing the pedal to try to get some revs and see if I can clear the problem but I cant. I lift the bonnet and pull the accell cable but nothing happens. I then notice this buring smell, a bit like burning plastic. I could smell it outside and also inside the car, but the smell didnt last long altho it was strong. So I tried to look under the car at the exhaust. The exhaust seems very high up on the car I wondered if maybe it was blocked or something, but there was a lot of pressure coming out. I could also see some fumes coming out the back of the back box.

Anyway, I thought I'd turn the car round and chug it home and as it chugged along at around 2000 revs, it began to ok itself. It seems to me that it did so when I had the clutch semi engaged. When my foot was off the clutch it went chuggy again and then seemed to sort itself once I had it semi engaged again. I cant be sure if that helped it or if it was just coincidence.

Any opinions. It's all related with previous complaints on this post subject.

Tacho reading zero and a burning smell. Sounds like the ignition amp or coil may be the cause, certainly electrical and in that region anyway. Worth carefully checking all connections in the ignition circuits.

This is a real shot in the dark as the Xsara may not use anything like this but often this problem on 205GTis is traced to the ignition amp overheating due to deterioration of the thermal transfer paste between it and its heatsink.

the software was CorelDRAW. I've booked it in at some auto electric place. I said I was skint and coulnt afford to fix it but I did want it diagnosed. They say it will cost £50 + vat per hour. Crikey thats so dear aint it?

I'm gonna phone up my local citroen dealership and see how much they will xharge to diagnose the prob.

Xsara rev counter is controlled by the ECU & the coil unit in the original picture is the later direct on top of plugs bolt on type.

If your coil pack has SAGEM as the make then that could very well be the problem :wink:

Arnold Clark, better off getting a 5 year old to look at it or find another dealer or Peugeot / Citroen specialist.

So you think it could be the hose to the map sensor?
If it’s a vacuum-related fault, yes.
If the engine stalls when you unclutch to stop at the bottom of a hill, then it’s high vacuum drawing in air through a vacuum leak.
From under the bonnet, go to fast idle, and if there’s any hissing or sucking sound Image from hoses or gaskets, it’s air getting into the vacuum.
You may explore the area with the can of Holy Water, WD40.
As per Malcolm’s trick, if the idle speed increases there, that’s where the air gets in, and now the WD40.

my money is on the throttle position sensor now, the first question was about the idle control valve which is about the idle speed, i think your problems happen driving too... how is the throttle cable? not sticking or catching anywhere?

The throttle cable is fine and doesnt stick. It's in the garage today to get diagnosed. £50+vat an hour. It's been in since just after 9am and now it's 12. I've got £200 and am anxious if I have enough money to pay it - whatever it will be.
