Rough idle , misfire cylinder 2 and random misfire only on idle , no light on

Rough idle , misfire cylinder 2 and random misfire only on idle , no light on Dash but logged on to ecu changed plugs moved and changed coil packs but when I unplug the maf I get no misfires can’t find any obvious air leaks ? Could it just be maf is gone ?

Update now misfire the same with MAF UNPLUGGED could it be carbon built up or injector ?

It could be a few things really. Carbon build up will be there, dependent on mileage, but it could also be injectors or even the HP fuel pump.

How does it drive? do you get a lot of cut outs, especially around 2500-300 revs at full throttle? If it's only randoms misfires then I would say it's probably carbon build up - but still could be HP fuel pump issues.

Mileage 130k only on idle that it misfire on cyinder 2 but when I was testing the misfire it did misfire on cyinder 3 one time and cyinder 2 misfire 0-100 0-50 per 1000 but when driving it was pretty much none on cyinder 2 drives amazing pulls amazing boost perfect jusr misfire at idle really lost tbh
