Hi All,
Sorry ive not been around, been away with work, anyway more updates and a little bit further down the line........
I got back in the car on Monday after my trip and started her up, immediately a lot of rough idling and misfires again. Had the car recovered to Sytner BMW in Nottingham who were happy enough to charge me £150 for what appears to be a 15 minute plug in (aka BMW Diagnostic report). Their computer said that all 4 injectors were misfiring, but please remember that all 4 have already been changed.
Anyway, I went and bought a brand new spanking set of injectors, all installed yesterday and the car drove lovely for about 20 miles. Parked it up over night and from cold start we have a misfire again......this is where it gets interesting.
Read the codes using Carly Pro and there it was, Misfire Cylinder 4, swapped over ignition coils with cylinder 3 and misfire disappeared, drove very very well, and using Torque Pro detected no misfires.....mmmmmm happy days.
Started the car from cold tonight and there it is again, rough idling and misfires, codes read again and this time Misfire on Cylinder 1.
So now I'm thinking that this makes no logical sense, a misfire can't just "jump" cylinders for no apparent reason......
I throw this to the floor lol..............
