Every time i get gas and then the temperature goes under 20° when I start my car the next day the check engine light comes on and stays on for 1-3 days. I took it to Advanced Auto parts to get a diagnostic test done and they said it had something to do with gas emissions into the atmosphere and that it was fine to drive. it didn't happen for a while but now it happened again my inspection is up next month and my car won't pass with the check engine light on. what can I do? should I be worried?
