take your car to autozone and get a free scan of the code. Once you get the code, look it up online for what it means and possible solutions. This will take away much of the mystery and you may be able to try some easy DIY fixes before going back to a mechanic.

I had consistent check engine lights with a toyota when it hit your mileage. 02 sensors went, then the MAF sensor. I replaced the MAF sensor myself (cheap easy DIY job) and reset the code and it was fine for a couple years. Since OBDII is all about emissions, I found that burning high-quality fuel made a big difference. My cat finally started to go, but the check engine light would come on and off. I could keep it off longer by using Shell or other tier one fuels.
