When I stop at a light the idle does not seem smooth, the tac says 600 never fluctuates but it acts like a miss but it don't. I have changed the plugs ,cap,rotor. I have cleaned the TB and replaced the IAC and adjusted to spec. Other than that it runs great at all other throttle positions. It is an 89 with 17000 miles. all stock. Any Ideas?????
