Toyota Hilux (no power over 2000rpm)

Hi I had a Toyota Hilux to look at, it wouldn't rev over 2000-2500 rpm, and had no power, the truck had no OBDII fault codes and no relevant Toyota fault codes.
I looked at live data to get a clue what to look at.
The MAF sensor PID was suspect, so that gave me a direction to carry out test, and confirm a fault with the MAF sensor.

(when a data PID looks suspect, I usually compair OBDII on the scan tool against the vehicle manufacturers data PID.
I may even compair the reading with another make of scan tool to save time chasing unreliable information.
I have even found OBDII to be unreliable on one scan tool and fine on another, this was a surprise to me because I thought it was always reliable)

I hope this helps someone, and thanks for watching.
