The only thing I can think of it being on you car would be plugs or leads.
The injection should take care of everything else, that is if theres a problem it (inj), it would be all wrong or nothing.

After a good run on the weekend, the mini has developed a mystery miss again. It sounds &feels like it is running on 3 cylinders when idling (Rough and irregular engine sound) and when not under load. Put your foot down and the miss goes, and all the power is there. What should I be looking at that may cause this ? Would an earth strap with a fairly frayed engine block end have any effect ? |

I'd be looking for a vac leak. It will miss at idle, then on open throttle theres no vac therefore no vac leak and all will run well. |

check that the inlet manifold is actually tight edit--> as in that it`s mounted properly---> all nuts/bolts are done up tight |

Have a look through the section relating to SPI/MPI on TMF. Has helped me with a few problems, there is a lot of good reading on there so make a cuppa have a read. Cheers Pete http://www.theminiforum.co.uk/forums/in ... wforum=140 |

Thanks for the advice people! I will pick up some new plugs this arvo, as I swapped back to an old set of leads and still had the same problem. I will also pull off the hoses from the manifold/ecu also and give them a check over. Now onto the uk mini forum for some 'light' reading 
Thanks! |

Turns out ALL the bolts holding the exhaust and inlet manifolds on the head were not done up. I was able to do them up tighter with my fingers before I even touched them with the spanner. Did the water mist trick after advice from local Mini workshop guy. |
