Check the plugs wires and coil.

How long has it been since it has been tuned up?

No it's completely standard and it's only started since yesterday other than than the car is fine no smoke no knocks or anything, Also the temp is fine so nothing sinister apart from this to be honest and the mpg has gone down a tiny bit that's it cheers.

Yes, it will set a boost code or MAF code.

If the light is on, start with a scan. So you don't waste $ on
plugs etc.
