Title: Misfire on 2.3 16v Post by Robby on Jan 21st, 2005, 6:56pm My car has been working normally for ages, but tonight it started misfiring. I think its down onto 3, possibly 2. Sounds and feels rough and stinks. The engine wiring harness was done about 2000 miles ago, so hopefully it isn't that again. Service was 3000 miles ago, the plugs weren't changed because they were ok - is it likely to be them, or is there another gremlin I'm likely to have encountered? |

Title: Re: Misfire on 2.3 16v Post by Phil_Waller on Jan 22nd, 2005, 12:06am Oh dear.. Do a search (not sure how good the search function is).. You will see lots of posts by me about this.. What is the harness you speak about? Is that the loom that runs up to and along the top of the engine? How bad is it?? |

Title: Re: Misfire on 2.3 16v Post by Robby on Jan 22nd, 2005, 10:28am The loom was the one that goes on the 16vs - The one that runs around the tp and back of the engine, I think it does the wiring to the injectors too. The misfire is really bad. The whole car shakes on any acceleration, and won't really go above 35. Going to have a look at the plugs this morning. |

Title: Re: Misfire on 2.3 16v Post by nick on Jan 22nd, 2005, 11:31am Leaving billing last year I lost a cylinder in my 98 estate. With the caravan on the back it was a b****r, but it turned out to be a faulty plug, a propper platinum plug, but it had broke down after only 6000 miles. Got to be worth a look, if not then coil packs are prone to go so check those next. hth nic |

Title: Re: Misfire on 2.3 16v Post by Robby on Jan 22nd, 2005, 11:53am Right then, plugs are out. The one on the middle cylinder that has an HT lead - not the one under the coil pack - is wet. All are platinum tipped, all have been in there a while, and the very thin platinum electrode has worn away on all of them. Curiously, the wet one looks the best out of all of them, but heres hoping its just plugs. Otherwise, could it be wiring? Does the scorpio fire a spark every 360 degrees, so it could just be the short HT lead or plug cap giving up. Please not engine wiring harness again. |

Title: Re: Misfire on 2.3 16v Post by nick on Jan 22nd, 2005, 12:45pm It shouldnt be the harness again, they last a few years, but plughs are a definate, I changed the lot while I was on, plugs and both Ht leads, as well as the other stuff filters and cleaned the maf, and I have had no problems with it at all. Now my 24v thats a different story,mmmmm Nic |

Title: Re: Misfire on 2.3 16v Post by Eddie on Jan 22nd, 2005, 4:10pm As ever,I reccomend twin electrode plugs for the 4 pots ::). If the 2.3 uses the same plugs as the 2.0 then NGK BKR6EKC. eddie ps My owners manual was printed before the 2.3 was born. |

Title: Re: Misfire on 2.3 16v Post by Phil_Waller on Jan 22nd, 2005, 4:40pm A wet plug seems odd. Do you wet on the outside or on the electrode it's self? Eddie - tell me more about these plugs - where can I get them from? |

Title: Re: Misfire on 2.3 16v Post by Robby on Jan 22nd, 2005, 9:12pm Right then. Changing the plugs did nothing, new HT lead on that pot did nothing. Garage picking it up on monday to have a look. They did the wiring loom, and the mechanic is a genius. |

Title: Re: Misfire on 2.3 16v Post by Robby on Jan 23rd, 2005, 10:45am Faulty coil is a possibility. Certainly preferable to having all that wiring sorted out once again. Scorpio electrics are a bit crap, no? |

Title: Re: Misfire on 2.3 16v Post by Robby on Jan 24th, 2005, 4:09pm Just phoned the garage. It was a coil pack. Getting the car back this evening. So I've had the wishbones, engine wiring loom, and coil packs done so far. Whats next in the list of quirky failures? |

Title: Re: Misfire on 2.3 16v Post by Geoff_W on Jan 25th, 2005, 10:11am Good question Robby, Just guessing, but something to do with airconditioning? Or perhaps just a weedy sounding car horn (its the puddles wot do that) ;D Make sure you lube the runners on your sunroof. Happy motoring :D Geoff |
