Clogged cat will cause these type of problems. So will low fuel pressure. Put a fuel pressure tester on fuel rail. Do key on prime. You should have around 43 psi. Start car & idle. Pressure should be at least the mid 30's psi.

Put car on an obd 2 scanner. Read the codes. There are codes that don't light the ses. And do a running sensor scan to see what sensor data is telling you.

Download 96 service manual at the following link. It will have a whole section on driveability & emissions. My Files
