I would second the AFM.  Spring for a new one if you can afford it.  They
wear out in the tracks where you use them the most.

The Aux wire upgrade is only for Digifant fuel injection which I think
started in 1986.

I would look at your AFM.  It could be starting to wear out.  Certain parts
of the sweep on the contact strip may be worn causing wrong resistence
feeds
to the ECU.

hey list--

having trouble with hesitation on acceleration...although idle/timing are
set correctly and, as best as i can tell, all sensors are functioning
properly and all vacuum lines are tight, my 84 hesitates and bucks on
acceleration...the hesitation has two distinguishing characteristics: 1) it
only happens in the middle of the power curve for each gear and 2) it is
intermittant, i.e. 1 time out of every 10 times i start the thing and drive
off, everything works fine...any ideas???...could this be a sign of a
faulty
ecu??...

also, and perhaps related, what is accomplished by installing the afm wire
upgrade??...i've heard about this a handfull of times and have seen one for
sale on ebay, but don't know anything about it...

any ideas or references to the archives would be appreciated...

many thanks
seth bruggeman
