it is now fitted just past the collector, it has started to idle low when ticking over and feels like its goin to stall. | |

having the lambda in 1 cyliynder primary is a bad idea. get a lambda boss put in around 3-6" from the collector. | |

I have had several cars in with lambda sensors in an individual primary and never had a problem. | |

if its on one of the single brances then you will get the problem.. had a 4-1 on mine and it would not pass an imisions test. put the old manifold back on and the problems go... always need to get a manifold that has the lambda/hego sensor in a collection point where all the gasses meat not just from one cylinder. | |

as i read it one of the single branches! | |

is the lambda sensor fitted after the collector (where the 4 branches join) or in 1 of the single branches? | |

my last lamber had 3 wires. its not a ntk one its a bosch (my mistake) | |

wires shouldn't matter 3 wire is just heated yours isn't! | |

quote: my old lamber sensor came into contact with water which fried my engine loom. fitted another loom but had to use the car for about 3 weeks without a lamber sensor. got my new one the other day and fitted it (to fit it where the manifold meets the cat i need to trace the wires back to the bulk head and re-thread them down threw the back of the engine) only thing i noticed when i got the new lamber was theres only one wire not 3, but apparently they dont do a 3 wire lamber for any corsa engine now, only the nove gsi/gte and the 2ltr's i fitted the de-cat cus the cat overheated when i didnt have a lamber sensor. | |

heavy on juice is because its running rich. | |

quote: manifold is fine no leaks, have got a de-cat, but that shouldnt cause it. am moving the lamber to where the manifold joins the cat so it reads all four pipes and not just the one. it has been very heavy on juice aswell. | |

nope shouldnt cause it! Any air leaks between manifold and head if its had a new manifold as that would trick the lambda! | |

have just fitted a new ntk lamber sensor, its fitted in one of the outlets on my manifold at the moment (have got a 4 into 1 exhaust manifold) could this be the reason? | |

I agree, sounds like a lambda problem | |

tbh that all suggests its running rich! | |

first you need to know if it is to lean or if the car is lying. | |
