Hey guys,
Did a service last night, fuel filter, plugs, and leads, oil and air filter and all fluids.

Found spark plugs looking like this :

I've checked for vacum leaks, cant find any...
need some help here to diagnose this.

Air flow meter? O2 Sensor? any guides to check for this stuff or what I'm looking for ?

Any help appreciated.
Cheers

If 02 Sensor was bung would usually be rich.
Same with Mass Sensor which if failed would normally put the car into limp mode, and idel weird.

Sparkies dont look to bad, check your timing maybe might be too advanced.

You can get Mass Sensor (flow meter) cleaner, does help sometimes.

I doubt you will get the colours off that chart with modern day fuels bar the oil fouled or excessively rich one

I wouldn't be running that engine to much until you sort out the problem, that's looking super lean.
