Check engine light
New to the forum. I bought a 2013 mlibu with 50 000 kms on it about 6 months ago. Love it so far.
Today i Sprayed my car down and cleaned her up nice. Was finished drying it off and I fire up the engine to an engine light on. I turn it off take the gas cap off and tighten it back on. Start it up same thing, light on. Turn it off give it a few minutes maybe 5 minutes I'd say. And it is gone this time. Drive for about 20 minutes and its back on. Could it be the gas cap seal is starting to go? I am going to get it checked out on my next oil change which is coming up. However just thought I'd get some opinions
