My Range Rover idles but when I apply the gas it sometimes bogs, sometimes completely sometimes almost completely, all injectors are cleaned, what could this be? It idles good, fuel filter?

I’ve attached a recording of it happening.Video of bog

Every time it drops in rpm’s it’s me hitting the gas.
 
So, from your attached video we see that the engine at idle of around 1750rpm, then there’s a few blips of the throttle and then after the revs drop slightly below the idle speed, then will increase back to 1750rpm… yes?

Also unfortunately i’m confused with your statement “when I apply the gas it sometimes bogs, sometimes completely sometimes almost completely, 🤔

When i blip the gas, instead of rising in rpm it drops, and sometimes dies. Only when i apply it slowly it rises normally.
