I have had my three wire O2sensors and AirFuel meter for quite a while but now
thought I have the time to do something about the readings.
I have a mostly stock BJ8 with Kirk headers, 10%ethanol. With stock needles, I
cruise one meter segment LED rich at sea level and at 2000 feet, the next
richer meter segment is flickering. Not so bad, I guess. The faster I go, the
richer I get in a gradual manner. However, when I climb a hill during the
cruise at around 70mph, the meter goes dead lean (one LED from zero). It
usually shows completely lean at hard acceleration also.
40mph cruise gives the same one LED rich as at 70.
So should I get some weaker springs first or try for a needle that tapers to
rich faster after the cruise?
The web stuff I see says to try the needles.
