what sets off check engine light? How bad does the problem with the car have to be to set a code? It is missing or surging like everything is fine and you get a slight loss of power. Also felt on deceleration.

You can get missing or surging easily without getting a light, especially if it is a spark issue. Burned through wires or plugs can run a long time and pretty badly without throwing a code. MILs only come on for very specific reasons, and the car can run badly for a reason other than those.

Depending if its ODB1 or ODB2, odb2 is more sensitive then the former. Cars throw a SES light mainly due to the a problem that leads to increased emissions, Misfires does combust fuel and air so hence more un burnt hydro carbons, there fore you get a light.
