I just recently bought a 2006 Ford 6.0 King Ranch and for the first week I had absolutely no problems. This week I filled up my truck and I've notice the truck has been burning a lot of fuel. I have only driven about 120 miles and the truck is already below 1/4 tank. The truck runs excellent when its warm but starting it in the morning it runs rough for a few minutes. The Egr has been deleted also have a mbrp 4in exhaust. I really don't know where to start, I love the truck but I didn't expect to have problems this soon. It also has about 213k miles on it, but please lead me in the right direction as far as this goes. Thanks
