Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My check engine light has been on for a couple of months now but car runs OK, however, lately I have noticed that the temperature guage goes up to about the half way point when I am sitting in traffic & not moving. What does this mean?

The check engine light is on for a reason you need to have checked. The temp half way sitting in traffic in texas , How hot is out there ? Do you have the air on too? This all has a factor in it. Have you checked your coolant level , I know it is warmer there than here in so. jeresy.
I am in GA and the temps have been cool, with the high's being in the upper 60's. No, I have not had the air on. Yes, the coolant level has been checked.
