Sounds like you may have an exhaust leak.LEXi73 said:yeah i have the same prob i think! i smell some kinda burning also. usually only small it once i stop at a light or stop sign for over 10 secs or so. some kinda burning kinda like oil. i do think that my car has been louder recently though so it possibly could be the cat. i was going to take it to the delier and have them look at it. also my rear defrost dosent work for some reason and get them to look at the bushings cuz they are way overly squeeky. hopefully all under waranty
