i've noticed my revs do the dropping thing more when i've got my music up loud, think the drain by the subs and amp has some effect on it | |

Same problem here with the revs droping then rising! Mine mostly does it for the first 20mins/30mins of driving - as soon as I take foot of the gas it goes real low, gives a shudder as though its going to stall then rises straight back up again. If anyone know which sensor casues this problem let me know please :thumbs: | |

My car does that every morning m8 but when warmed up it goes away, its probably your lifters but give it a full oil change first to see if that cures it. | |

yeah mines the same as urs, 1.2 16v ecotech, to be honest the oil thing sounds interesting cos I think it cud do wiv topping up plus I'm gonna totally drain it out anyway and replace it wiv sum new stuff the only thing is I know nothing about oil. | |

Mines a 1.2 16v ecotech and it makes the most annoying tapping noise all the time, well, nearly all the time!! My prob is that it comes and goes, i mean it taps mostly but then sometimes it'll just be totally silent as though there's absolutely nothing wrong with it which makes it even more annoying! Started a few months back, flushed the oil, put in semi synthetic 10w40, made no difference so i'm guessing my tappets are knackered...its on a S99 reg aswell with 50k on it! bloody thing. With it coming and going i'm not sure whats wrong with it cause surely if it is the lifters or tappets then it would tap constantly and not go away. The whole revs dropping thing, same on mine, only sometimes though, will drop right down then come back up to 800rpm again. | |

this happened on mine a few weeks back. i checked the oil and it was VERY low. i also noticed that when i took a corner fast the oil light blinked for a second. | |

when was last time u changed or checked the oil. that sound is made when the oil is gettin round the engine when u first start it. when mine first started to do this i gave it an engine flush and oil change and i was lucky it cured it. worse case is likes been said a new set of lifters or tappets or even the tappets reseated. | |

when ever I start my engine now from cold and its just idling there a ticking/knocking noise comin from the engine, sounds as if theres a loose bolt or two somewhere just rattling around in the engine! |
