I would start at the pedal end, engine will only do what the pedal asks of it.
If you have access to diag kit you can see what percenttage the throttle is reading.

The flap in the intake is for the emissions kit, many cars are running with this removed.

I'd replace the pedal, as it sounds like the demand sensor is faulty.
