What make the check engine light come on in 98 caviler?

What make the check engine light come on in 98 caviler?
Check engine light means an emmisions problem. Could be a mis-fire in your cylinder head (Bad spark plug or wire) to a bad 02 Sensor, to bad fuel, to lean or rich mixture. Any number of things. GOTO AUTOZONE, ask for a FREE ENGINE TROUBLE CODE CHECK, (aka O.B.D). They can tell you what is making it come on, and how to fix. Anytime I had this happen, it was because of a bad spark plug or Spark Plug wire. Cheap fixes.
