pellet-type cats
on pellet-style gm cats (this one is 1982), the pellets should be clearly visible with the refill plug removed, right? i pulled my plug, because i couldn't hear any rattle when i banged on it. sure enough, i saw nothing but the waffle-looking baffles, top and bottom. i failed emission inspection for high CO. i know it's probably because it's running rich (but very nicely). but would sticking a new monolithic 3-way on there be enough to get by? my CO numbers were about twice what they were supposed to be, and all other numbers were great.
Thanks for the inputs guys !
