Oh yeah, DO NOT remove those two screws near the plug, you will rip the wires off the circuit board. Ask me how I know To remove the plug take off the wire clip around the plug.

Ok, I tested the AFM and it all was good except for the E2-Vc. It is supposed to be 100 to 300 ohms and it is 0.3

I checked over them once again to be sure and came up with the same results. So according to this the AFM has a problem. But shouldnt it cause a CEL to come on. I have no codes

The problem im having is a major lack of power and stumbling. I can barley get up to 60mph. The engine lopes very badly at idle.

Well the time I ripped the connectors off mine the CEL came on and I could only go about 5 mph. You might try opening it up and see if anything looks wrong, maybe a little cleaning would help.
