Unhappy Check engine light...again

OK so I have a 1997 Mazda Protege, and about 2 months ago my check engine light went on so my dad told me to bring it to the Mazda dealership so I did. 3 hours later I ended up paying them $130 to tell me that I needed a new catalytic convertor and that was what was causing the check engine light to come on. In my province it is legal to drive w/o a catalytic convertor so I havnet replaced it, and the check engine light went away after a day or 2, but just recently while driving my check engine light came on.

My friend has the stuff to diagnose this but hes away right now so im just sondering if the light came on again since that convertor still hasnt been replaced.

Thanks.

Try disconnecting the battery for a few hours and then reconnecting it back.
Should solve.

Disconnecting the battery for a couple of hours is a waste of 1 hour and 59 minutes.

Good thinking.
But it depends on the car injection module.

instead of paying, or waiting for your friend to read the codes, autozone or advanced auto parts will read the codes for you for free, or you can even rent the tool off of them.
