Hi All,I decided to have another look at this mini after the workshop quietened down for summer holls. As before the car runs fine when cold and as soon as it warms up miss fire on cyl 1. To recap,the head has been done,valve seats checked and all good.New set of rings,vanos units changed,solenoids checked,injectors switched around,ecu replaced with a known good unit,coil packs and plugs replaced. Cyl head off again to see was anything missed. But all good.Now I have discovered that when i disconnect one of the cam sensors the car runs fine.It starts, runs like a new watch.not even a hint of a miss fire, idles like a new born baby. The only indication of a problem is engine light is on. I've been driving this car for a few days now and not a hiccup. Connect the cam sensor back up and we're back to square one.Can anyone throw some light on this.

Thanks in advance
