Just got my truck back from the dealer, still not running right

[bpb424]

I took my truck to the dealer for hard starts, blue/gray/white smoke, shuttering on the highway and poor fuel economy. The replaced the EGR valve, EGR cooler and flashed my FICM. I just picked up my truck and it still shutters slightly on the highway and it has a rough idle. At first I thought it was because the engine was cold, but once it warmed up it continued to do it.


before I picked the truck up I asked if they tested the head gaskets and injectors and he said they pressure tested the system.


oh and now I have a popping under the front end when I turn or accelerate.

Any ideas? I have called the dealership twice and they won't take or return my calls

fuel filters maybe?

[fordmasterdieseltech]

dont call them, take the truck back to them and have them recheck it.

[bpb424]

I wish it was just fuel filters. I changed them 4-5k ago

the truck is on it's way back now
