We have an ongoing problem the the 206. Sometimes when its cold it loses power. Usually my wife or I (depending on who is driving) will pull over, turn it off and on and it'll be fine for the rest of the day. I've realised that usually when that happens the Catalytic Converter fault sign comes up on the display. I thought either its at fault or its not rather than being intermittent. Would it be worth having it cut out or replaced? Would the engine management cope with it being removed?

That is an incredibly environmentally irresponsible thing to do, and probably not the problem. More emissions from French bombs is the last thing we need, get some proper diagnostics done.

Its a toss up - possible more kms to the litre with it out. We had it at a Pug specialist and he can't locate the problem. " French bombs" we're not talking Rainbow Warrior here.

You know it's due any day now don't you? Has the French Military somehow pre-programmed all the French cars to work for them?

I had my suspicions and I am half Dutch so that doesn't bode well. (least we forget it was the Dutch guy who died in the Rainbow Warrior).

My brothers one did exactly the same, took it to 2 diff places, they replace coil pack. Still the same. I read up and did a flush and oil change to correct oil. 0w something, look up on Castrol site and all good now.
ETA it was throwing up the anti pollution light and ringing a bell.

Get it scanned first! It could be a post cat sensor, otherwise cut and rip the honeycomb from the cat or replace with a small resonator.

Run it on 95. it's that 91 crap that's causing the fault. Jap cars can compensate to handle 91. Euro's cannot.

Thanks for the ideas. Its been scanned but a fault can only be picked up when its happening - which it only does intermittently.

Troggy--does it show up only when the car is cold? or is it not related to engine temperature? Im thinking of two possible senarios. 1) wrong oil viscocity is causing problems. 2) Inside the cat is close to clogged up and the extra moisture when car is cold is enough to tip it over the edge. I'm no comfortable saying remove the cat and fit a muffler in its place because I just don't know how sensitive that French stuff is to changes like that.

and if you did get it scanned it would show up No 1 or No 3 cyl misfire, that's what my brothers kept showing. He left it with them for a week till fault showed. They couldn't fix it. As I said, flush and oil change sorted it. Google it and you will find it is a lifter problem (o:

Jimma-fair to say that with it literally being sub zero here (troggy is about 1km from me) some days would emphasise the lifter issue?

no i looked at a older thread and i cant be stuffed try and figure out what year model pile of franch crap you own but i can tell you a few generic true answers even do it might just go swoosh over the top of your head when i told you about parts swapping is a moronic idea . Now fact 1 a peugeot specialist who dont finds a problem on the peugeot = clearly not a specialist

My Grand-daughter had a 306 that did this.
So I did a bit of research to see what the problem might be. The Cat light generally means that there is un-burnt fuel in the exhaust beyond the cat converter.
In the case of her car, the problem was that the car was not correctly correcting for temperature as it warmed up. The temperature sensor worked, but read low.
So it would start rich, but the ECU didn't see the temperature come up, so kept the mixture too rich, for too long.
This caused the car to run very roughly, and the pollution light to come up. Restarting the car would cure the problem.
I don't know why, but assumed the ECU would look at the temperature, and decide it was warm enough not to need high levels of enrichment.
So a new temperature sensor cured this.
But I can also see that incorrect oil could do it if it meant a lifter was not correctly working (thus lowering compression to the point where fuel wasnt all burning), as could a faulty coil, plug lead, plug or similar.

It has been on the a scanner (I did write this above) with a specialist. When we got the car it wasn't running well so 1 injector and the coil pack has been replaced. It goes really well now apart from this one issue. Certainly I seriously consider what oil and changing it soon.

maybe if the poster had put--In MY experience euro's don't handle being run on 91 whereas Jappas do it would be more PC. DEFINITELY in my experience with euro cars from early 90's to mid 2000's they dslike running on less than 95 octane. jappas on the whole seem not to mind 91 at all. I dunno if any exceptions with euro's but Subaru product doesn't like 91 either

i have never met a euro that likes 91. i always recomend 98.

BMW 540i 1998 - been on 91 all the time, no sweat. In addition, the cat in a 5 series starts to rattle when it needs replacing. My BMW guy said $1500 to replace it or $500 to take it out. Downside = bit smelly (haven't noticed it) bit noisier = not a downside at all. Upside = better consumption, slightly more power. Computer takes care of any tuning issues.

Cheers. On my watchlist but probably for someone who is more likely to use them. The cases are cool.

Thanks for your thoughts on this. You've certainly put the effort in.

you should change oil and filter soonest if what they replaced was faulty then your oil will be having a ton of petrol in it and making it act up with the petrol fumes burned via crank case breather A professional would have advised that the oil will need to be changed even if it was only in there for 1000km. that is based on that what parts they replaced where actuarly faulty for real.

Oui monsieur. I'm happy that we do agree,. but I wouldn't say 91 is complete rubbish, it's no good in them french cars but.

Q? troggy-recent aquirement-and missfire repaired-any long out of town runs since owned?-e.g. aucks to hams?

We NEVER go out of Auckland. Why would you?! Longest trip - Henderson to Ponsonby.
