Wow, reading that gave me a headache.
First thing, do a FULL tune up, using A/C delco parts only. Then do the Ultimate TBI mods...they are listed as a sticky.
While your at it, install a straight through type muffler, like Magnaflow, Borla, or dynomax. Stock pipe should be fine.
When thats done, drive it for a while, and see if you like it.
As far as OBD1 locking up? Thats a line of crap.
