the smokes Brown/Black when idleing its fine it only happens whilst driving and can happen almost immediatly when pulling away or driving along it feels like a carberatta blockage as if its going to backfire.

But if the EGR valve was stuck open, the amount of air being drawn past the MAF would decrease and the ECU would pull fuelling accordingly.

You have a split intercooler hose that is leaking air downstream of the MAF which is resulting in overfuelling.
