Golf gti Auq 1.8t, slight misfire and uneven idling

[carl1.8t]

Hi
The coil packs were replaced by Vw as part of a recall a few years back. The car sometimes misfires under acceleration and the idle can be lumpy at times. Never owned a turbo petrol golf before but can anyone give me some advice? Plugs and fuel filter very recently ( 2 weeks ago) would it be worth putting injection cleaner in? The coil packs aren't the red top or the bolt down ones
Thanks in advance

Misfires are usually caused by either a faulty Maff (air flow meter) or dirty or corroded contact to the air flow mater which is causing faulty readings.

or faulty coil packs or those new plugs could be faulty ?? was the misfire there before the plug change ?

EGR valve also

if stuck open, will be lumpy when cold
