my check engine light stays on. I thought it was the gas cap so I changes it. Light still on. I also took off the battery terminals and put them back on. Still light is on.

First thing you need to do is have the codes read, Autozone does it free, Post the results with the code number(s). Even if the service engine light is not on, there should be freeze frame data stored.
If it won't make it to Autozone, buy a cheap scanner, they can be had for 30-40 dollars, a good investment, since they cover all cars sold in the USA from 96 on.
If the light is blinking, it means possible damage to the Catalytic converter. Misfires. Service it right away!

If you can post the actual codes they should be P XXXX, this is the only way I could tell you where to start.
