How many miles? Mods? Do you have a scanner of any kind (Edge Insight, SCT, Ect.)? What color is the smoke? When you removed the EGR cooler did you block off the up-pipe scoop? Does the smoke still smell sweet after EGR removal? Do you have oil in coolant/coolant in oil?
The U0306 code means that your ECM strat and your FICM strat are incompatible. When you had your FICM replaced who did it? Are you sure that is was programmed? If you buy one from Ford you have to have it programmed as they come without a strat. If you bought one from Ford and put it on yourself then this is probably part of your problem. If that happened then you need to go kick the parts man in the b*lls for not telling you that it had to be programmed.
P0269 and P0272 are cylinder #3 & #4 contribution/imbalance. I had the P0272 and Rev-X fixed it. If the injector is too far gone though, you will have to replace them two injectors. I would try Rev-X first though.
