ALL CYLINDERS MISFIREING

2008 Mini Cooper S • 41,000 miles

Ok so this prob has come and gone for a few weeks its ok than I get the codes again and a rough idle
It has stalled on start up some times and I have replaced. All plugs and 2 coils no difference also had a valve cover gasket leak replaced that than he throttle body still the same issue than I replaced the tensioner for 3 weeks was great. Than it came back and worse than before rough idle and still stalls on start up some times. The code reader is telling me all cylinders are misfireing I don't know what to do please help if you can

The Cooper S has direct fuel injection, and there is a very good chance that carbon buildup is causing your problem.
