I searched the board and it says something about a DPFE Sensor Upstream Hose off or unplugged. I have checked all the hoses on the EGR and the silver thing that loooks like a fuel pressure regulator with a hose ontop of it and its plugged in. Should i check anything else?

The Check Engine light keeps going on and off, usually when i rev it up over
4K rpm
