I once asked the dealer if I could put a locking gas cap on my car. The mechanic told me changing my gas cap would result in the check engine light always being on.
http://autorepair.about.com/od/troub...ghtarticle.htmCHECK ENGINE. There's nothing fun about those two words. There's also not a lot of logic to be gathered from them. Check engine? Could they be a little more specific? Nope, they can't. That's because the Check Engine light comes to life if anything, and we do mean
anything isn't 100% under the hood. This means that you could be staring at a major repair, or your gas cap could be too loose (no kidding).
I have my fingers crossed for you cloud!
oh and P.S.
When the mechanics did a OBD scan what was the code?
