Hi guys, my 2.2 D has started to blow black smoke out the exhaust when I accelerate reasonably hard, the engine has done 107,000 mls.


It also sounds like its missing when the engine is cold after an overnight parking until it warms up then its fine.


I'm not sure if these are related, it was serviced last June but didn't change the glow plugs, recently had a new mass air flow sensor 12 months ago.


Any ideas?
