Title: Bad idle Post by pools on May 19th, 2009, 3:26pm Hi there! I found this on the site. http://www.fordscorpio.co.uk/cleanmaf.htm I have the same symptoms, bad idling when cold, high revs when hot. And the transmition wont change gear from third to fourth. (aut.) But, I have the 12V engine. What to do then? Can somebody help me? P. Olsson Sweden. |

Title: Re: Bad idle Post by tonyboy on May 19th, 2009, 4:04pm Hello. You could clean your MAF with some carb cleaner, but i think i would start by looking at the transmisson fluid first, see if it's a pinkish reddish colour and not a brown colour and smells like burnt chip fat..... |

Title: Re: Bad idle Post by pools on May 19th, 2009, 4:25pm Ah, sorry! I've checked it, measured with a ohmmeter. It seems to be good. |

Title: Re: Bad idle Post by adzst24 on May 19th, 2009, 4:28pm Hi Have you cleaned the idle control valve yet ;) Adzs.. |

Title: Re: Bad idle Post by Simmo on May 19th, 2009, 4:33pm There is a detailed diagram Here (http://www.fordscorpio.co.uk/12vlooms.htm) which may also help. Sometimes taking the large connector apart and cleaning it with contact cleaner will improve the connections. |

Title: Re: Bad idle Post by pools on Aug 20th, 2009, 11:51am Hi! I'm back ::) I now have checked the Idle Control Valve, the Lamda sensors, cables and vacuum leaks, but nothing. ??? Any ideas? Thank's, pools |

Title: Re: Bad idle Post by Snoopy on Aug 21st, 2009, 7:25am YOU DO NOT HAVE A MAF ON THE 12V The symptoms you describe are from my experience synonymous with a faulty IACV . ie. bad idle when cold and high tickover revs when at running temperature. Make sure all the vacuum pipes are connected and NOT leaking especially the one under the IACV . The 4th gear on the 12v is controlled by vacuum from the pipe under the IACV http://www.drich2422.ukfsn.org/Vacum_pipe.JPG if that is NOT connected or leaking then you will not get 4th gear engaging. |

No, I've now tried that. But no leek in this or any other vacuum hose. If I take it apart, the engine runs a little bit better, but not good. Also tried other hoses, but no change. The IACV is also checked. Any other ideas? Thank's pools |

Title: Re: Bad idle Post by Tompion on Aug 26th, 2009, 1:12pm You may need to clean the IACV a couple of times - work the piston back & forth to force the cleaner through the hollow spindle into its chamber. |

Done that. If I disconnect the IACV the engine dies. I can keep the engine running if I give more gas, but it runs very bad. |
