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?
