I don't think i have a choice, I just replaced one (one closest to the firewall), and i think it's clogged again. And i can't afford another. I'm gonna do the intake manifold/secondaries cleaning to fix the root problem, but i don't think the cat issue will clear itself up on its own.

98 contour 2.5 GL no mods, just trying to keep it running till it's paid off. Then the fun will begin.
