I've had the same issues. Check the easy things first, exhaust leak (I've had the flange on the header crack and not seen until removal) replace crush gasket, check silencer packing, check for intake leak.

Get a tuner and check for any fault codes. Test sensors per the manuel.

If that doesn't work my ultimate fix was to increase the co level to +5. You'll need the oem fi tool not the gytr tuner to do that. Good luck

I'm going to guess valve clearance. Not too many UK guys on here... You're probably best off with your closest yami dealer.

 

It's FI so the getting isn't off...
