P0174,runs rough, looses power, but not always

I have tried flushing out my heater core by flushing it out using the outlet hose.

Then I was going to try changing out the blend door using a kit and cutting through the heater box with a dremel tool. I was able to cut around the heater box only to notice that the blend door is working fine.
