in fact scrub that, it could be a huge number of things. Fuel filter/pump? injection problem? | |

the knock sensor is also very simple on its design, meaning its not very likely that it is faulty. | |

it is a crystal based sensopr in the back of the block betwwen cylinders 3&4. senses 'pre ignition' or 'knock' on the engine. it allows the engine to run as close to the 'knock' point as possible, therefore allowing it to run very close to the optimum timing for efficiency and performance. | |

ok sorry i got it wrong, but its to do with adjusting the timing to run correct for the octane rating of the fuel that its running on... correct? | |

Well the knock sensor just reads the octane rating of the fuel and adjusts the ignition timing to match, so it may cause a missfire but wouldnt affect fuel economy i dont think. | |

has anybody have this go wrong with their car? its causing my car to slight misfire and a lack of power throughout the rev range especially after abot 5000 rpm, and its drinking fuel, is this what it should do? |
