It's like it looses tune at about 4mths and I have to re-tune it with the map.
Do you do the basic maintance ?? ie oil change and filter change at the time of the bog?
I noticed I had a slight decline in perforamance a few weeks ago ( ongoing slightly) and i did my last oil change and looked at my airfilter
... What a winter breakup will do!
Just a suggestion.
