:( I thought all was going well, she's just passed 150k, so no youngster, but recently she's been misfiring under WOT.
Scanned today, no error codes at all.
Pulled the plugs, plug 1 very oily and quite loose to unscrew, others fine.
Replaced them all and took for a fairish drive, fuel consumption WAY better and engine smoother.
Re-scanned no errors.
But, that oil on plug1 has me concerned about gasket / seals etc.
What should I Do next? Just monitor it?
