Right i will go with ICV then, its clean as a whistle though... Im right in thinking its only the spring and piston part of the ICV that can be cleaned as that is clean? Their is also a small grub screw that alters something (what?) on the throttle I think. Maybe thats set wrong? Yeah it definatley only does it when the car has been stood for a while, If i drive it all-day then by the end of the day I dont have any problem at all! Cheers guys, i'll go get a new ICV 2moz, £20 from scrappers :thumbs: | |

If the air flow metre was at fault you would get a problem when driving it, and performance would suffer, not just a idle when cold, when the ICV is working...... | |

Oil level isn't oil pressure. | |

Yeah how, ive always ran with oil level on max. Last oil change I slightly overfilled but im just leaving it to burn off... Could this explain why it does it when cold but not hot? Im thinking it could be Air flow meter as I used to have a induction kit & swapped back to standard. I bet its the induction oil that you spray on the cone, it will have gummed up the AFM? Cheers guys, any more oppinions would be cool. Im not going to buy the valves/sensors new... scrappers for me. :thumbs: | |

could be gambit... i always thot it was the IAC (idle air control valve) but could never hav been assed to get it fixed.... doesn't really do any harm tho its jus embarressin when you start her and she idles really low.... but really good if the cops stop you about the zorst and sask you to start it..... got away wit it a couple o times cos when i started her she idled low for a while..... zorst aint that loud but its just da cops are comin down hardd on the local young guys | |

yep minendoes exactly the same thing. i thot it was cos i had filter and zorst but now i no its not...... i no this sounds crazy but if you put your foot BEHIND the accelartor and pull up it'll stop (obviously not a permanent fix but does 4 the mean time)..... crazy but true!!!!:thumbs: | |

Asked many time, will try MIG too but im running a 1.2 XE engine with NO mods. No management light is on but the problem is when I come off the gas the revs drop REAL low, almost stall, then it comes back to normal (approx 800 RPM). It never does stall though. Other than that its fine, and petrol consumption and emmissions are normal. It tends to do it worse when its just started or cold for some reason. Its got to be a sensor or valve but which? Air Mass Meter, Throttle position sensor or Idle control valve? :thumbs: |
