I just got a '90 Honda Accord LX w/ 148K miles to pass CA smog tests w/ flying colors!
Replaced the 02 sensor, catalytic converter, PCV valve, air filter and spark plugs. The EGR valve was removed and cleaned. A can of Sea Foam in the gas and half-can directly to the oil before it was changed.
Link to data including smog test results is
here. Nox went from 536ppm to 5ppm! CO from 0.68% to 0.00%!
