Blocked injectors??
Run some injector cleaner through it.

Blocked air filter and/or MAF sensor??
Replace air filter and clean MAF (carefully) with MAF Cleaner ONLY.

Faulty Throttle Position Sensor (TPS)??
Check for codes and replace if necessary.

Check vacuum hoses for leaks/connection.
Replace and or re connect hose/s.

EGR valve
purge hose fell off
fuel pressure regulator
leak in fuel rail.
02 oxy sensor

on top of all the things listed above check your fuel pump too.

Get a fuel line pressure test done.

EGR valve

That could prove to be tricky on a 96 VS given it doesn't have one.

Does it run rough cold hot or both?
