1986 Chevy Monte Carlo V8 Two Wheel Drive Automatic

First off happy holidays. Alright I just picked up an 86 monte carlo. It starts on the first flick and runs smooth. The "service eng. soon" light is on, and seems to come on when I drive it, but not on when first started/warm up. When first warming up it smokes white, but then goes away, Im guessing cause its in the 40's to 50's temp. What on the Monte triggers the ''service eng.'' light?
