6.o l l76 Rich and rough on startup

[Baz123]

Hi Guys,
My 2010 l76 6.0 liter has only just started playing up when first started in the morning. It blows smoke (strong smell of fumes)and misfires for about 10 seconds then all is good. Only done 65000k, regular maintenance, 2 rounds injector cleaner, new air cleaner. Don’t know what’s causing this cold start issue...anyone experienced this? Thanks in advance Baz

Is the car flex fuel, i.e. can run e85 ?

Video would help, start with bonnet up show misfire then ‘smoke’ out back.

No flex fuel...mechanics think it is a leaking fuel injector...
