hello, I have a problem and I don't know how to solve it, if someone can help me, I have a fitech 3003 installed on a boat,
the afr marks 20.6 I have looked and changed the gaskets, checked the o2 thread in case it had leaks,
and it's still the same, I have changed the engine for a new one but the afr after a few seconds in operation goes up to 20.6
does anyone have any ideas that can help me? thanks. on the handheld it doesn't show a fault.
