1985 pickup smog

have a 1985 22re 4x4 toyo pickup and i am trying to pass smog the firsts test i was way off on timing but i replaced the throttle position sensor (notorious on toyotas) and it was better but now i am a lot closer but still cant pass i am going to replace the plugs and airfilter. and probly check the EGR but is there anything else i should do? Any suggestions? and also anyone else have this problem? any help would be much appreciated thank you very much.

Your actual numbers?

And the limits in your jurisdiction?

Pretty important to know those.

Not enough info. What about the HC and CO numbers? Don't be so stingy.

High NO is excess oxygen, overly advanced timing, or a lean-biased oxygen sensor.

Check for exhaust leak before the cat.

Heh, forgot something: Check for proper EGR function. Valve stuck closed, clogged passages, both will increase NO emissions.
