After he told me I consulted the Google and sure enough, there are opinions that say such a CAT will lead to hesitation and surging, which is exactly what I had.
He said the new cat was an improvement but still not perfect. He had to put in a T connection with nipple on the fuel line in order to test the pressure. He said it was only at about 6 or 7 and it needs to be 13. New fuel pump. Runs ideally now.
While the tank was out he looked it over for crud, said it looked pretty good. Took out a few bits of something.

is your o2 sensor precat or post? I could see the O2 fouled or a post cat signal being bad and giving poor readout to the primitive ECU. Unless it was actually clogged, I dont quite understand how that fits together, especially if its precat at idle.
