WHOOT WHOOT, got the car back today. The reason why the cat had a whole in it was because I drove around when it misfired. What happened was when the unburned fuel left the motor it happened to ignite in the precat therefor it busted up a hole in it. When I got there, their head mananger told me that he had to fight for me to get mazda to pay for it. Mazda said that they dont want to pay for it because I had no previous service records but the dealership pulled through. I think he fought soo hard because he knows that im only 17 and it would take me a long time to pay the $500 dedutible that mazda wanted me to pay. So yeh the dealership arent always wanting to rip you off. I would also like to say thanks to everyone on the forum for giving me suggestions on what too do. Im so happy and now my MP5 drives beautifully. I love it.
