     You refer to 1 of the 3 AFM  measurements being out of spec, can
you be
more specific.
 I assume this is the air flap AFM type  which is a  special varaible
resistor
with a number of parallel resistor taps at different points of the arc.
If you
measure the resistance it does not provide a smooth increase / decrease
in
resistance .
 You can change the calibration of the AFM by altering the spring
tension acting
against the flap, but you should really do this on a rolling road so as
to get
the right mixture accross the whole load range.

Yes its a Flapper type AFM. I took off the top and had a look, Looks
like the resistance that was out is the circuit through the AFM that you
talked about. The "wiper arc thing" I adjusted the
tention 3 notches tighter to lean it out, it seems to have
helped a little, The plugs are still a bit on the rich side, I did not
measure the resistance after I changed it, I will. I think that this
is part of the problem but not the entire one, Im going to measure the
fuel pressure as soon as possible.
