1987 Chevrolet Caprice 5.0L Poor Idle Quality, Hesitation, Surge, Cuts out, MIL Lamp on
engine has surge, mil flashes in time with surge. after
MUCH diagnostic effort, problem seems to boil down to
timing control. timing goes from 4deg atc to 20 btc in time
with the surge (i think this a symptom of the problem, not
just a result of rpm change).
