Check engine light was lit. Went to have my care serviced for oil change and filter, and my mechanic told me that my gas cap was not properly closed or I need to replace it. I bought a new gas cap and it solved the problem.
Gas cap seems to be loose. Won't fully tighten like I'm used to on other cars. Last time the check engine light came on I took it to a dealer and they said the code was a vapor leak. They reset the code, but now the lights on again. Probably time for a new gas cap.
