ive already fixed y pipe .cleaned turbo,cleaned egr valve,replaced map sensor and hose,cant think of anything else at time any help would be much appreciated.

Is there a Ford dealer near you? This sounds like a situation that'd be very difficult to diagnose over the computer.

the white smoke would be a head gasket most likely, but for some reason the EGR would have a role in that too. (sometimes that would dump coolant into the oil for some reason im not exactly sure why this design does that.) but a dead miss or a rough running condition would be caused by an injector or the injector wiring harness, maybe a burned wire. :humm:
