The problems started recently, and the Explorer seemed like it was bogging down a bit. It was acting like a bad EGR valve. At the time, I didn't have the money to fix it, so I left it, and suffered with the annoying CHECK ENGINE light on. I checked the codes the other day, and got Insufficient EGR Flow detected. I have replaced the DPFE, the EGR Valve, and the rubber hoses that connect to the DPFE. I have verified that all the hoses are in good condition and connected. Could the EGR vacuum solenoid be my problem?
It suppose to have vacuum if not check from the solenoid to the intake manifold

I have replaced the egr vacuum solenoid and reset the codes. It still comes up. I know its getting vaccum, because I pulled the vacuum plug off the egr and put my finger over it while holding the throttle at about 1500 rpm (a guess). I could feel it pulling. Any ideas?

The computer controls the solenoid when to open and close-

I replaced under warranty the EGR, which didn't fix it, but the warrantied DPFE did.
