Hi guys been a while since I've been active sorry, anyway a few months ago the car developed a misfire in cylinder 1&2, someone said try driving maf-less I did this and she drive perfect again, so I assumed maf at fault, I ordered a new one and decided I'll give her a service (filters and fluids) put the new maf on and again the misfires are back :@ same cylinders, when the car hits boost if feels like it holds back and bounces around (a rocking sort of feeling) and it the pumps out black smoke as trying to push through (think black smoke) and also sounds like a boost leak when at this point but I've checked for any oily residue from the "leak" any help or opinions are welcome
