As you can see your angle actual and voltage are inverse from each other and move with each other. You want to compare throttle to accel pedal. I think its doing what it should be doing.
Looking at your fuel, I don't see anything wrong. LTFT are +/- 1%. STFT are +/- 4-6%. This is totally...

If I had to guess I would say your throttle body is the cause of your surging. your MAF is following your throttle and the throttle is...
