I meant to remove the multi-plug connector, or is that still a bad idea? |

If you unplug the connector on the ICV the engine will just rev up as the solenoid will have no power to be able to extend and block the hole to create the correct gap for idle.________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

If you remove the power to the icv it will just stick at the position it was at when power removed, had this on my 309 I converted to run a gti6 lump.you will find it will idle ok cold, but as the engine warms up the idle will go sky high, mine was up near 4000rpm swiftyboi006 wrote: If you unlplug the icv it will let in air so no The electrical plug he's on about! ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

Alright, so disconnecting the ICV won't really achieve anything then. Thanks |

Is there a test you can do with regards to the MAP sensor, something about removing it then start car up ??________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

Going by the sensor test FAQ, it has to be connected while testing. I'm not sure how I can get to the contacts on the plug without destroying its cover or splicing the cable, which I don't want to do. |

Has your meter not got sharp pointy ends on it?Just stick it into wire if so ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

I'll take another look tomorrow I hope and take a pic, silly weather the last couple of days...The shroud around the plug/wires doesn't look like the ends of the probes can fit into it, but I'll give it another chance tomorrow. What should the readings be? I found this video, not sure whether it shows a good or bad MAP response. http://www.youtube.com/watch?v=M_tk6WtXcO0 |

If your not happy sticking the sharp point on your meter through the wires you could stick a pin into each wire,then use your meter on the end of these ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

In the FAQ about testing the map sensor it states 0-1.5v fluctuating,so looking at that vid I would guess aslong as your voltage goes down when you increase the revs your map sensor is working?  ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

So eventually I gave up and went to the garage. They replaced the ICV and MAP, no dice.Then hooked it up to a diagnostic PC - all values from all of the sensors are ok. The tech did mention that the ICV housing's seal is iffy, but he didn't have one on hand to replace to so he just turned it around, and that didn't really help. So the current suspects are the seal and if that isn't it, then possibly the ECU |

Well the car is back in my hands for further testing. The rubber seal on the ICV housing was replaced and a new ICV was installed. So far it seems to be running smoother, both in idle and while driving. Will be doing some driving around this weekend to see if it actually solves this problem.The leak was indeed of coolant, from a cap on the rear of the engine, was fixed and refilled with new coolant, so nice job spotting it beez_neez_gt  So I wanted to just say thanks to everyone for their help and their time helping out a complete noob :p |

Could have been both a bad ICV and bad o-ring. Or maybe having the bad o-ring somehow finally "killed" the ICV? I only tried it once today, one cold start to drive out of the garage home and I didn't notice any irregular high revs, also when I came home with engine at temp I turned it off and started up again 2 minutes later, which used to cause it to cut out. It started and idled ok.Tomorrow I'm going on a drive of about 20miles in each direction, going to a local french car club "Clean/Clay/Wax" meeting. So we'll see how it behaves then. |

Well so far the car behaved alright. Plenty of warm starts and it seemed to run ok now. Going to see how well it goes this week.On a side note. Got it washed, clayed and waxed today  Also met the first, original owner of my car by a complete coincidence. Small world we live in. |
