I have a 1992 civic si with 299k miles STOCK other than a aem cold air intake at the time I got my vehicle smog and this is the results of the test.

%CO2--%O2--HC--CO(%)--NO(PPM)
@15- 14.2--0.7---35-- .01----- 2686 gp
@25- 14.6--0.2---8---- .07----- 1727 failed

prior to smog I replaced spark plugs, o2 sensor, changed oil and filter, ran sea foam, and less than 1000 miles ago I replaced sp wires, dist cap and rotor. had 1/2 tank of 91 octane. Prior to smog drove vehicle for 15 miles, let vehicle run while waiting for smog to be done.

thank you
