hey guys so I could use some help if possible I have an 04 f-350 so heres my problem when I start it in the morning its a little slow as usual but it sputters almost like it wants to die but then it picks up and its puffing a lot of white smoke i have an sct programer on the truck so I started with reading the codes and I got one for the MAF sensor and something about the KAM memory I replaced the MAF and im still having problems with it it sputters while im driving a little. it feels like it has no power or its not getting fuel but after its been run for a little bit the sputtering goes a way for the most part I have no idea what it could be any advice would be much apreciated. thanks
