Pumping the gas does nothing for a fuel injected engine.

If it's starting when you're holding the gas slightly, the TB is probably past due for a cleaning.

Ah, '96 is a combination of OBD I and II codes. None of those are P codes, so they're unrelated to the issue.

The TC code is a C code, the AC code is a B code. Not sure what the SD code is, probably a B code as well though.

No it's 4 numbers - OBD II. They just displayed oddly on the DIC in '96.
