Any ideas what this could be please?

Couple of weeks ago turned the car on and was running rough, and made a spluttering sound like the vid link I have put up.

All ran fine then yesterday it ran even rougher, sat there q
10-15 mins till warmed up and then was fine for the rest of the day, but still doing the spluttering /blowing noise when came off the pedal?

Sounds like a blow in the exhaust but had it checked and apparently seemed ok.

I have added the YouTube link of what the sound was like when I rev it.

I would start with the common issues first.

Check for air/vac leaks and the first place I would be looking is at the PCV valve.

Ok mate will do, thought the pcv was more high pitch sound? I had someone mention maybe the turbo? And all videos I've seen about knackered turbos are all winey noises etc this sounds like a blow?

Haven't had it long tbf and has been serviced well but dont think the spark plugs/coils been done in last 2 years possibly.

But that doesn't quite explain the vac/air leak that can hear.
