Virgilson, how many miles do you have on your celi? It could be time for a new cat, or you could wait until right before your next smog test, which is probably coming up soon since you have an '00.

If anyone cares...three-way catalytic converter is basically just the catalytic converter since three-way is a type of cat and that's what we have. "Three-way" refers to the three regulated emissions it helps to reduce -- carbon monoxide, VOCs and NOx molecules.
