I’m driving to Orlando and I just filled up in South Carolina. Check emissions light came on. Pulled over and tightened gas cap. Any ideas?

 

Many gas stations have moved to their winter blend gasoline mix. It's likely your oxygen sensors picked up some sediment. Either way, stop at an Auto Zone or other Auto Parts store and have them pull the code for FREE so we don't have to guess what sensor went bad. Get the actual code and post it here. Then we can help and not guess.
