remember,the closer you are to the perfect
A/F ratio,the wider the "swing" will be.The
problem is you can't see it with the scanner
-you may only see high numbers then all of a
sudden you'll see a low one and say"where did
that come from?" when in reality,it has been
swinging back and forth all the time,but the
scanner just hasnt "caught"it.thats why this
info is useless-I'm not sure I am getting
across what I'm try'in to say,so thanks for
being patient.
P.S.I forgot if your scanner monitors
"cross counts"-that is the number of times
the O2sensor is crossing over the "median"
value of 800mv this is a "real time" reading
relative to the baud rate of your ECM(year)
the '84&85's are real slow,but'86to'88 are
OK
