I have a 2011 skoda fabia 1.2 tsi 105 hp, and recently it started misfiring at idle, the weird thing is that i have replaced everything (coil packs, spark plugs, cables, fuel injectors and fuel filter)

it lights up the ESP light and the low thre pressure and then it stars to idle roughly…. But as soon as i go the roughness is gone! 
if anyone had this issue please let me know

Look for air leaks such as brake servo hose splits or PCV pipe breakages. I think the latter are 'to be expected, sooner or later' on the 1.2 TSI.
