 the basics and check timing and fuel pressure....fuel pressure is good but
 timing is 22degrees with est plug disconnected(should be 0)....so I attempt
 to move it back and it doesn't like it...dies every time....I notice on the
 diacom that the IAC counts down to 0 AND the diacom shows 2 >>

Check to make sure the magnet thingy plate hasnt spun on the distributor 
shaft. Seen that a few times. Pop the cap, see if the thing spins.  Symptoms 
include varying timing, sometimes it will run w/EST unplugged. It will sound 
retarded/advanced depending where the plate stops.
