Well, something that works very well in these cars sometimes causes this failure is that the air filter is clogged and causes more gasoline injection which causes more catalytic gases which causes the catalytic lights to come on. The first thing is to change the air filter and in a quarter tank of gas, put a divine catalytic like Cataclin and Beran which in most cases works very well.
