Hi Coby,
I to wish for a CO exhaust =
tester but
cannot justify the cost of one. I have found that if you =
adjust the
afm (air flow meter) main spring tension so the disconnected O2 =
sensor
reads 0.55 - 0.60 volts with the engine running at 3k rpm then =
adjust the
idle bypass screw for the same voltage at idle all seems to work well =
and
functions good.
The Bosch L-Jetronic system =
with or
without O2 work well with the above procedure also. Of course on
L-Jetronic without you must install an O2 to get your =
readings. A
heated O2 will work well even in the tail pipe.

Note. Always mark the gear on the afm main spring so =
you can
return to the original tension if needed.
