Car spitting and revs down when throttle press

[Anthony182blue]

Hi everyone,
See if anyone can help me with this issue in my clio 182.
The car has recently started to stutter when pressing a tiny bit the throttle pedal and the revs would drop too. It doesn’t happen always but sometimes turning it off and back on will fix this.
Throttle body and acceleration pedal has been changed and nothing happened.

The car used to start as soon as the key was turned and now it takes just a bit longer, and sometimes when starting the car when the key is released the engine would sit at really low rpms for a sec and then revs up to normal.

Ive also noticed that when engine cold and coming to a stop the car will revs up to around 1700rmp and then back down to 800/1000rpms…

No lights on dash.
Coil pack and leads brand new, NGK.
Coolant temp sensor brand new.
Spark plugs few months in. The NGK ones.

Ive updated a video of the car when pressing a tiny bit the throttle pedal.

Any help would be really really appreciated, this is really making my head now!
Thank you so so much guys!

Before chucking any more parts at it, id get some diagnostics done with can clip. Id start by looking at the lambda and map sensor data.

Might even be an injector on its way, mine used to stutter a bit then injector failed.
