Hello and thank you for your time. I just purchased a 02' Trailblazer and 3 weeks later I noticed that my check engine light was on. I am wondering what it could be?

For starters have the PCM (computer) scanned for codes, Autozone will do it for free. If the PCM sees a problem it will store a code that will help in diagnosing the problem, get back with the exact codes
