well after resetting the cel in my mothers car of a P0420 the weekend before thanksgiving, it has come back this past week
there are no other codes and I monitored the exhaust sensors and compaired to my 99 and they seem the same.
now I am going to assume that with such a short time between cels for a P0420 that it is definately the cat that is bad
now the federal warrenty covers all the work that needs to be done? I know we might have to pay a diognostic fee, but other wise we don't have to pay anything right? also did anyone else have a hard time getting the dealer to cover this? the light is on now but I don't know how long it will stay on as last time it was only on for a day before it turned off
