I had a similar problem with a 1989 Corvette especially at low idle like at a stop light. After much heartache and several mechanics left scratching their heads (including a GM Corvette certified mechanic), on slick mechanic determined that the torx bolts on the tune port manifold had loosened slightly causing an air leak which allowed more air into the fuel/air mix. Since this occurred after the mass air flow and other sensors, the computer could not compensate and it simply wasn't getting the proper fuel/air mix. Tightening the bolts to the specified torque cured the issue. He knew the torque requirements and unfortunately I do not.
