smog fail
#1
1993 sidekick 1600 cc 16 valve.
Will not pass smog , No2 too high.
new EGR , new EGR modulator new Cat

TEST #1 replaced cat
No2@ 15 mph should be 568 (PPM) max. tested 1273
No2 @ 25 mph should be 821 (PPM) max. tested 994
TEST #2 reset timing from 8deg BTDC to 5 deg , rewired fan to run full time, used up fuel and refilled with 92 octane. ( high NO2 is from high combustion chamber temp)
15 mph NO2 went from 1273 to 939 PPM (still too high)
25 mph NO2 went from 994 to 814 . That passes (821 max)
TEST #3 new EGR and new EGR modulator
15 mph went from 939 ppm to 1581 FAIL
25 mph went from 814 (passing) to 1497 Fail

Please help , I do not want to loose my sidekick
