Mine does this too. Misfires like mad when cold, till I blip the throttle/put it in neutral & floor it, and it's fine for the rest of the journey again, gives full power and pulls well - really, really irritating.
Mines had a new coil, did nothing, leads are fine, so not an issue, no fault codes either. The strange thing is it only does it when the car is stone cold - if I come back to it after an hour or two, it won't do it - it's only after 6+ hours it seems to play up. Hope you find a fix for it though, would be interested to know the cause of the issue.
Help needed on last straw with polo but dont want to give up

If you look down the side of the inlet manifold, to the left side, you'll see a sensor that goes into it. Its held on by hex bolts / torx wtv you call them, and there isnt much space to get it out either. I sprayed some electrical contact cleaner from halfrauds onto a cotton ear bud, and patiently took my time to clean the sensor out.HD9POLOGTi wrote:Mines a 6n2 as well pal and ive replaced pretty much everything my last option ive just been told about is the map sensor any tips on cleaning it ??

Word of warning..
DO NOT USE CARB CLEANER TO CLEAN THE SENSOR.
