ENGINE LIGHT WILL NOT GO AWAY

Ford F-150

I have a 01 f150 4.2 2x2 5-speed man. About 6 months ago my engine light came on. The code came up EGR pressure and bank 2 fuel too lean. I changed the EGR valve, sensor and solenoid, and I also cleaned out the tube from the exhuast to the EGR valve. A day after clearing the code the light came back on. To make a long story short i'll just tell you what I replaced through the 6 month period; Coil pack, maf sensor, spark plugs & wires, and both O2 sensors. After changing all these parts, my light is still coming on with the same code a day or two after I clear it. I am at a loss. Can you please help.

I would be checking for a vacuum leak, if you are getting a code for 1 bank only I would be looking at that side of the inlet manifold to start with.
