The last time my check engine light came on I took it to the dealer only to find out it was because the gas cap wasn't on tight enough. So when it came on a few days ago, I have been debating on whether to ignore it or make the dreaded trip back to the dealer.
I found out that AutoZone does free check engine light diagnostic tests.
So this afternoon Erin and I headed over there. The guy followed me out to the car with his little gadget thing. I assumed he needed to get under the hood, so I opened my car door and popped the trunk. Oops. And he didn't even need the engine, he just plugged his gadget in under the steering wheel. I felt kinda dumb.
And yes, it was the gas cap again.
