sooo... looks like you need cats and the air pump, along with all the evap non-sense and the EGR spaghetti farm. if you wanna do it dress-right-dress, that is.
they never had air pumps to begin with. why would they need one now?
the other question is, were they ever allowed to be sold in CA. to begin with? they were not allowed to be sold in some states from a lot of things i've read over the years. something about the exhaust. i always figured that was why there were so many here in the north east.
