Il check later.

Yeah I've a rev2 turbo.

Pulled spark plugs out yesterday with not even 600 miles on them and they were coated in carbon so cars running rich.

So trying to get yo bottom of it, or checking if it's normal.

Mods are full decat and exhaust, uprated intercooler, blitz air filter, boost at 1 bar.

Is it normal to be running this rich? Can smell the petrol too but put that down to decat.

Air flow meter is good.

Thinking it could be O2 sensor.

If it was, will I always get a fault code cause there are none at the minute
