Annoying misfire at light load, please help

kakluote

Ready to race!
Got issue of misfire when
with light step on the pedal in low rpm

it only happens on the light step on the pedal, and at low rpm which below 4000.
No misfire at heavy pull....

While after unplugging the power cord of maf sensor, misfire gone...

The misfire happened with or without WM open. But this issue happen after i intall the WM.
it looks like leakage but can't find where...
Any idea⁇
thanks in advanced
