Long time viewer first time poster!

Recently my car has been sounding quite rough when accelerating from cold until the engine is up to temperature. Sounds quite raspy. Once its up to temperature it goes quiet so I'm hoping its nothing serious its just starting to annoy me more and more

Used INPA to see if any fault codes could help but had none though on the rough measurement option it showed cylinder 1 and 4 to be used a lot more than 2 and 3.

I don't have much knowledge about engines to this point so don't know if its normal or not so I shall link to photos of the readout.

If this is normal any suggestions as to what may be causing the noise? I really have no idea.

Any help will be appreciated.
