Stutter between 1500 - 2500 and black smoke?? Help please
Am new to the forum, as I only got my Alfa a few months ago (it's my first YAY!) and i fecking love her. Best looking car I've owned.
But she's sick and worrying me.
Over the last few weeks I noticed a stutter in second gear around the rev range above, but this has spread across the gears now.
I was buying fuel from D4 fuels (sounds dodgy I know) until I read last week about what cheap diesel can do. So I filled up two days ago in Esso and added a diesel engine cleaner treatment.
This morning I noticed not just a bigger cloud of smoke than it used to have under acceleration but pretty thick black smoke.
Looking for some ideas or assistance. God I hope it's nothing bad.
