vag comlog and codes... im stumped

[slammeDUB]

heres the story, was getting misfires at idle...found vac leak...fixed the misfires at idle

now up top in the rpm range i get bad fluttering and codes come up as such
(sometimes different cylinders come up misfiring)
but here is one log

Address 01: Engine
Control Module Part Number: 8D0 907 557 N
Component and/or Version: 1.8L R4/5VT MOTR HS D05
Software Coding: 06201
Work Shop Code: WSC 06335
5 Faults Found:

16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-10 - - - Intermittent
16688 - Cylinder 4: Misfire Detected
P0304 - 35-10 - - - Intermittent
18014 - Rough Road/Engine Torque Signal from ABS: Electrical Malfunction
P1606 - 35-00 - -
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-00 - -
16688 - Cylinder 4: Misfire Detected
P0304 - 35-00 - -

so im thinking if a vac leak caused it to misfire at idle, would a boost leak cause it misfire up higher in the rpm range? it seems to only flutter under boost conditions.

motor is brand new (rebuilt) with 155 comp +/- 5% across all 4 cylinders

let me know what you guys think.

also the motor has new coilpacks, ICM, CTS, MAF, plugs are gapped right, Cam Position sensor, newer used turbo (minimal shaft play)

replace your number 4 coil pack to get rid of the misfire.

well how come i get, misfires in other cylinders on different logs, i have tried the replacement of coilpacks and switching them from cylinder to cylinder, sometimes ill log misfires in 1 or 2 or 1 and 2 or 3 or 3 and 2 or on this particular log it was 4 coming up yet there was still random multiple misfires meaning other cylinders were misfiring...
