When the "check engine" light is on, there must be a CODE stored in the ECU. Go back to the dealer and ask them to check it out. The CAT on 97 Civic should be still under the Emission's Warranty if I'm not mistaken. Remember, DO NOT give them a "Go Ahead" before they are sure what the cause is. I used to work at six different auto shops in Ottawa, I know that a lot of guys got more muscle then brain in this trade, no matter how long they are in the trade; what they do is to try different things at your cost. I've emailed you my phone number, feel free to call me.
