Hi Guys one of my Minis is a dead stock 2012 MCS with 67,000km Lately when cold staring it does a little of the pop & bang out the exhaust as if it was in sport mode. Then after a few cold starts the codes come up. I swapped ignition coils from my other 2012 but no change and the coils from the car throwing the codes work great in the other car.
I know its a misfire in cylinder 1 & 2. The car runs great and it will not throw the codes if it never cools down before you start it.
Using the Carly app.

Any ideas ?
Thanks in advance
