Would you believe that you can actually fail a smog test(emissions test) due to your gas cap not being up to standards? Yes, it is true people because it happened to me today...haha! Now, fortunately there's a Toyota Dealership right up the street that I could get a gas cap for my car. However, my car is a 1996 Toyota Corolla and I doubted that they had many 1996 gas caps lying around. BUT, they did and even though it cost me another $25.00 I went back to EZ LUBE and passed my SMOG Test. So, now I can pay my registration and be settled for another year. It's amazing how just when you think you have money or you are pulling yourself out of debt something always comes up...POOP! :)
