reading codes

I was wondering if I could read codes from a flashing check engine light on a 97 LS? or do I need a scan tool? I use to be able to jump a couple leads with a paperclip on my old ford pickup which would send me through a bunch of flashing lights that could be interpreted into a engine troble code.

I don't think so. That's pretty old technology that I think went out when OBDII came in. Go to Autozone and get your codes read for free.

no, that was done away with obd I, your 97 has an obd II computer
