I think vaccuum leak and/or exhaust leak.

Subject: Your early Morning/digifant/digitool brain teaser

Ok, here are the facts.

Yesterday got the 88 running (turned out to be shielding on O2 sensor green
wire touching connector, thus giving ecu constant lean signal) adjusted
mixture and idle per bentley, all seems well............drove around half an
hour or so, no probs at all running great..........no black smoke when
giving hard throttle, etc.  Seemed OK

This morning I take it on a long run to do some work, and come slowing down
to a red light, in drive (automatic tranny) Konks out.  Starts right back
up, but is hunting badly( tach going feverishly between 800 and 1200 rpm) I
look at digitool, O2 sensor readings, -.26 to -.39...........Give full
pedal, very hesitant, little bucking, and vroom off I go till the next
redlight.  Same procedure.  This only happens when motor is fully warm, and
the temp 1 and temp 2 sensor digitool readings are where they should be, as
is the AFM.

Any ideas?
