If you have an EGR, check for clogged egr ports on the valve or a leak (NOx). Make sure your ignition is completely up to snuff--good wires, plugs, cap, & rotor (HC.)
But really if you can't figure it out, the best first money you can spend is to take it in for a smog diagnosis--the guys at the smog check station may be able to suggest a shop. It will be a lot cheaper than just randomly replacing parts.
I had a Fiero with emissions problems, it was a worn out catalytic converter. Replaced the cat and it promptly passed.
