2004 Honda Civic Check Engine Light
 

Hello. I have a question. I have an 04 Civic Lx and the Check Engine
Light came on. The car was driving perfect before it came on. It seems
like when the light is on, the car has issues switching gears. I am
pretty sure that the gas cap is on tightly. The light shut off for
about 10 minutes, and was driving fine, until the light went right back
on. Could there be something seriously wrong with the car? Or could
that light also indicate that the car needs maintanence?
I am a little over due for a tune-up. Can anyone help me out?


Thanks,
Elizabeth
