using the search is good. Its been covered a bunch of times. Dump a bottle of "Guarantee to Pass" and take a nice drive. Give it a couple good WOT starts to heat the cat up then good right to the ref.

 

These things will help each time you take a smog test.
Change your oil
New air filter
New plugs/wires/cap/rotor if worn.
run a fuel system cleaner a week or so befor the smog test. Techron, or BG fuel system cleaner*(available only at car dealers. contact BG to find a supplier close to you)
Hope this helps
