Well my 1985 Sport Camaro idled very funny, it had to be revved up to keep it running and sometimes it would idle perfectly, and the motor's idle would fluctuate going up and down. It turned out to be caused by a MAP sensor, it's located under your distributor cap.
Probably in need of a complete tune up.
