Hyundai Repair: Check Engine Light, change spark plug, hyundai accent


Question
Hello John,
I have a 2001 Hyundai Accent and about month a go I did the following to it:  oil change, oil filter change, spark plug change, and air filter change. It runs great, but the "CHECK ENGINE LIGHT" keeps coming on and off.  What could be the problem?

Answer
there might a sensor going bad on it or might be a mounfuction going on. Take it to a parts place to have it checked out or if there a warrenty on it take back to where you got it from.
                      Thank you,
