I did the Oasis report from the link here. And found that within the first month of this truck being bought the engine was replaced along with the injector loom? Very strange. And then I think at about 30k miles the Oil/Egr coolers were replaced. I havnt really had any major problems wiht the truck other then back when the Odo and Speedometer were acting funny by shutting off or flipping 4 miles per every one I drove. Got that fixed. Found some connections under the fuse box were loose.. have cleaned the EGR and put in new O rings. But that was about 7k miles ago. Maybe I should check that again? Had the Turbo serviced because the vanes were stuck. Ford cleaned that and replaced a ring in that. cant remember what one it was though.
Then the Fuel pressure regulator started leaking. Ford fixed that also. Jusrt since then the MPG has been even worse. (Question) with the regulator leaking. Whould that cause the Fuel prssure to drop and mess up the injectors? or anything else I should worry about?

Wife has the truck today so Ill try to get into Ford this week or next. Need to find someone with a Scanner so i can check codes if its throwing any.
