Hello,Would a decat cause the CO to go up to around the 7.3 mark or could there be another problem thats causeing this high reading ?

That sure is high as it should be under .3 My old system went well over the limit but then the lambda would kick in to late and then the reading would go down but still kept failing emissions due to it going over instantly. Im guessing until the pressure built up for the sensor to read emissions where if you have a cat the pressure is there trying to get through it. ________________________________________ V6 Power!Faster I can go the better!

Well, that sounds like a typical high reading when using a decat, so I'd say yes.________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

 No way is that due to a de-cat!!!!  That is down to a knackered sensor, coolant temp probably  That level of Co will give you bore wash, and glaze the bores if your not carefull. My rallye with a de-cat fitted nearly passed the mot on emissions, just slightly to high. ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

 I read that as .73... As Coskev says 7.3 is far too high and will cause issues.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

So would you suggest i get a new temp sensor and a lambda then go get a quick emissions test somewhere local to avoid anymore mileage than i have too?So what is the limit of CO with a cat and without a cat ? ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

you can test them, see the FAQ.with it running that rich it's probably running like a bag of spanners, so when you replace the faulty item it should be quite evident ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I havent got one of those testers so is there any other way of testing it ?They are cheap enough though so ill get one anyway and hope the rich wont damage the lamda. Saying that though the engine on ide or start up did cut out twice. Also the engine did overheat a little bit when i had an air lock which is now sorted out, would that do any damage to the CTS? ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

Should not damage the cts Co should be below 0.5 on a cat equipped car, below 3.5 on a pre-cat car  ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

Ok thanks Kev, the idle seems fine and around the 8.5mark. Although on cold start up it doesnt seem to go any higher up and as its garaged thats warm i thought thats why it wont choke up on cold start up but it must be the CTS.________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

As said i could not remember if i did buy a new ECU temp sensor and iv just found i did as i did a thread about buying one earlier this year So it looks like the lambda is at fault ? ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

Yeah easy if you know how to use a multimeter and actually have one to use Surely if the idle is fine except not going up high on start up the sensor would be fine ? As said it has cut out on me a few times on start up but then i restart it up and it works fine, so intermittent. ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.
