Check engine light is on? on 2002 Chrysler PT Cruiser

My check engine light came on last week. it went out for about a day but has been on now for a couple of days. The manual says i can drive the car for a few normal cycles to see if the light stays on. please advise.

Check out RepairPal's article on the check engine light for what to look out for:

That should give you all the background you need to figure out what you need to do.

You should get it checked out, continuing to drive the car can cause damage to other components, especially the catalytic converter. You can get the codes read out for free at some parts stores, then post the codes here and we can give you a much better idea as to what is going on.
