Help needed on last straw with polo but dont want to give up

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.

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.

Word of warning..

DO NOT USE CARB CLEANER TO CLEAN THE SENSOR.
