Subject:Fw: AFM Tuning... Re: Me and our '88 are glad to be back

I see how this could be confusing.  You're right I did mean that the spring
tension was reduced, which then advanced the position of the "wiper" further
forward.

I should add that yesterday I discovered that the plug connecting 4 wires to
the AFM had very poor wire attachments.  It has the "power timer"
connections, (anyone know if these were original or a dealer installed
recall?).  The wire to Temp Sensor I (intake air temp) was down to one
strand attached to the connection.  I removed all 4 power timers from the
plug block (which was a bear to do), and soldered the connections.  As a
result, my previous AFM setup is no longer spot-on.  I've got better low end
torque, but I think I'm going to find that moving the AFM wiper by 4 notches
was too much.  Probably going to have to fall back to 3 or 2.  I'll post
what works.
