- Not yet fitted, but I do have one and it will be fitted when I get round to doing the mini-overhaul (have a week's hols to take before long). - Unfortunately not. There was a T4 at a garage a short distance from me but no-one there was qualified to use it on a Rover 75 apparently.. T4's are in extremely short supply over here (and T4 operators, even more so) I'll keep digging at it anyway. Cheers, Karl. Last edited by The Mighty Quinn; 13th January 2019 at 23:22.. |

Hi Andy, Yeah, it seems I'm the only one that has encountered this issue But I think the first two images in my earlier post show the bend in the fuel rail fuel pipe pressing against the body of the alloy inlet manifold - keeping the bolt holes off-centre. Not that big of an issue in itself - just doesn't look very tidy. Cheers, Karl. |

The 'box ECU can be swapped without the need for a T4 session. You just have to make sure the replacement is from a car with the same engine to ensure the software is correct for shift patterns etc. The change was initially beneficial but the old traits returned, much like when it would reset the original ECU.

How'do Karl
r.e Vacuum Leaks - it may be worth checking the Manifold is sealing properly at both Gaskets the VVC Manifold is a bit heavier and really requires the Support Bracket - this could be causing an issue Paul. |

Thanks for info, Richard. I'm quite certain that the autobox in my car is in physically good condition, as the oil that had come out previously (last year) looked quite good and the car has never been abused in the 110,000 miles (of 140,000 total) that I've personally completed in it. I have a new old stock ECU for the 1.8T autobox - I'll probably swap them over when I'm doing the solenoid kit swap, which I hope will bestow some better shifting traits to the box. I'm going to take a good look at all the wiring harnesses in the engine bay too when I'm doing the fuel rail, to see if I can nail down the cause of the misfire.. I hope to report some good news over the next month or two Fingers crossed Cheers, Karl. |

Have you checked the resistances of the solenoids etc. in the gearbox?

Thanks Paul. Yeah, I'll definitely fit the support bracket soon - will see if this makes any difference. No obvious sign of any problems at the manifold gaskets and no coolant leaks there, but the bracket was designed for a reason, I suppose, so fitting certainly can't do any harm.. Will report back any improvements once I get properly stuck back into this thing again Cheers, Karl. |

Hi Richard, Yeah, I'd checked those way back and they were all within tolerances at the time (although the figures since escape me). I'm not convinced that resistance figures will show up all issues that a solenoid might be suffering from, but rather just tell you if it's failed entirely or not..? Might be completely wrong on that - they say a little knowledge is a dangerous (and expensive) thing! Will fit the new solenoid kit and gasket when doing the mini-overhaul. If after all that, there's still no joy, then I'll probably just retire the car. No mechanics here have any interest in diagnostics work, unfortunately Cheers, Karl. |

Could easily be one duff plug failing under pressure in the combustion chamber.

I changed all the ignition components (inc. plugs) some time ago, to little effect. But I will check and change again (as needed) shortly. Plugs looked decent when I checked them the last time - see attached (these pics were taken some time last year, or possibly the year before ) Cheers, Karl. |
