Title: funny things happenning.... Post by invernessguy on May 23rd, 2006, 1:03pm Hi all, Ive got some trouble with my beloved again.... She runs fine afround the town, idles as normal, and accellerates ok, but take her out on the open road.... different story! Any sign of a hill, or under load, at 50mph+ and it just dies.... feels like its out of fuel? No sign of a missfire, and if i dip the clutch, and give it a rev, its ok again.... any ideas guys? Im aware that most of you will suggest an obd check.... Its not very practical for me, as nobody around here will touch the car (for a reasonable price) for a diagnostic check...SO, any good old fashioned ideas out there, to put me in the right direction? My money is on a fuel pump failing, will anyone back me up? In case anyone doesnt know, its a 2.3! Car has been fully serviced with ford parts last month, including new plugs. donnie |

Title: Re: funny things happenning.... Post by invernessguy on May 23rd, 2006, 1:54pm Fuel filter was replace3d at this service, i always buy ford parts and get them fitted by a local mechanic... I have asked him about this problem, but car not booked in to be looked at till next week...... If i can diagnose it before he gets it, it saves me money, and his time! My thoughts are a weak fuel pump? Car has done 130000 miles, so not excessive, but i suppose parts can go at any time. donnie |

Title: Re: funny things happenning.... Post by jonnycab on May 23rd, 2006, 3:34pm I had a similar problem on my old 95 Scorpio, but not as severe. The engine would feel like it was holding back. I thought it might be the fuel pump as it didn't feel like a misfire & only happened under load. To cut a long story short...it ended up being the coil packs at fault. It's worth considering. |

Title: Re: funny things happenning.... Post by invernessguy on May 23rd, 2006, 5:56pm thanks for the thoughts guys... more likely a coil pack, might try to get a hold of one to try. not likely the throttly plate highlander, as it usually happens on steady throttle... the car just seems to die a bit, then when the load is off, will rev freely again. A couple of times the car has stalled completely, but i have bump started it again, while still on the move ;) Cant do very much till car goes into garage next week, was hoping it was something that could be diagnosed easily, so i could have the parts for the garage next week, but really has put the damper on long runs, as im scared to go too far in case it will stop completely!! donnie |

Title: Re: funny things happenning.... Post by invernessguy on May 23rd, 2006, 5:58pm thats what it feels like mr floppy, as though car is running out of fuel? so many possibilities, i know its gonna be a hard one to figure out without obd! |

Title: Re: funny things happenning.... Post by tintin on May 23rd, 2006, 6:40pm had a very similar thing on my audi, eventually wouldnt start at all. turned out to be the spark arcing across from the lead to the earth terminal on the coil. lick of nail varnish across the burn track and jumped back into life, full power. |

Title: Re: funny things happenning.... Post by jonnycab on May 24th, 2006, 1:01am When I changed my coil packs I took a chance (I didn't know for definate that they were the problem). It was just a guy I picked up in my Taxi (said he used to work for Ford) who noticed it & said "yea mate, thats your coil packs". On his advice (in desperation & hope). I went & bought two coil packs from Ford (£60 each). He was bang on....... The only trouble is, I dropped him off at the end of a dark alley, & he dissappeared into the night...never to be seen again.......so don't know who he is.....but must be out there somewhere. |

Title: Re: funny things happenning.... Post by Simmo on May 24th, 2006, 6:58am Donnie, As you say the car was recently serviced have you checked for any loose pipes or even checked that the plugs are (a) tight,(b) the correct ones and (c) correctly gapped ?. If I recall correctly, all these points have been the cause of problems in the past. Could it be that in doing the work some part of the loom has been 'disturbed' or even a connector that may need a clean. |

Title: Re: funny things happenning.... Post by invernessguy on May 24th, 2006, 10:23pm Thanks again for all your thoughts guys.... I am beginning to suspect the coil packs myself, as yey i have not taken the covers off.... but will try and have a wiggle around before the weekend. As the problem is intermittent, i cant replicate it with the vehicle stopped.... might try and find a small person to go under the bonnet while i drive at 70 and maybe beep the horn till when happens, as a signal for them to wiggle the wires? But seriously.... its possible that the loom was disturbed while fitting new plugs. They were the correct ones, i expect they were correctly gapped, and tightened up ok. I have every faith in my mechanic. Had a quick look around for loose pipes etc, nothing obvious. I expect that the problem is causing obd codes, but i have no way of reading them here. donnie |

Title: Re: funny things happenning.... Post by Thunderchild on May 24th, 2006, 11:20pm Hi Donnie, sorry to hear about your troubles... could it be the cat? Not unknown for a cat which is breaking up to give these kind of symptoms. Hope you sort it out soon or maybe just go to the pub?? Geoff |

Title: Re: funny things happenning.... Post by tommy1340millar on May 25th, 2006, 1:09am mine was also doing that . Let it build up and no prob, but ask it to 'give it some', it used to just plonk itself down on it's big fat arse. cracked exhaust manifold and new cat. failed mot on Co2, diagnosis new cat. When my mate went to fit the new cat, the exhaust manifold almost came off in 2 bits. He welded it, re-tested the car, but cat was still dodgy. now car goes very well. hth, tommy |

Title: Re: funny things happenning.... Post by Simmo on May 25th, 2006, 7:04am The 'fault finding' page does say that the symptoms could indicate the cat BUT it could also be a plug problem. Fingers crossed for the latter!. |

Title: Re: funny things happenning.... Post by howiedintheplace on May 25th, 2006, 8:19am Does sound like the ignition is breaking down under load. If it was fuel it would do it all the time not just under a sustained load usally. |

Title: Re: funny things happenning.... Post by Paulus on May 25th, 2006, 10:20am I had a similar problem too. It turns out that I had some dodgy connections on to the coil pack. They were all corroded. I stripped back the wires and re-soldered some new wires into the connector plug. Success. MUCH cheaper than a new coil pack. ;D |
