its got an induction kit on, but thats been there for 2 years with no bother. i've done all the obvious... plugs, leads, oil change. i've had a similar problem before and that was an air leak which i sorted. but can't find one this time. i don't really want to go spending huge amounts of money sorting it out. i'm selling it in the next couple of weeks. The engine management light's not on. | |

it should idle about 800 rpm there are a couple of other hings you could do like cleaning the air intake and the throttle body cos you may have a slight blockage. | |

simply disconnect the battery for an hour so all the memory is lost from the ecu then after that time connect it up, start then engine.....but dont rev and let it idle for a minute or two hopefull this should sort it out, then all you gotta do is reset your clock and tune in your radio again and your away! | |

the cars a 1.4 16v. When you first start it, the engine is hunting between 750 and 1200 rpm, this settles down after a while. but then when driving it steady, it hesitates and almost feels like a mis fire. i've done plugs and leads, but still no joy. any help would be appreciated |
