I ran the car for 15min with 4th grear 4kRPM before i did the smog check. used one can of octane booster 54 miles ago, my number is very close.
Valves adjusted?
Did u try Clean Power?
My car failed again today. Thangs I did for the last 2 years.
-new O2 sensors
-new OEM spark plugs
-Sea Foam last year
-oil changed 2000 miles ago
I went to another Smog shop today and it passed! The tech using 1st and 2st gear and it passed with flying colors!:biggrin: The previous tech use 2 and 3rd grear and it failed all 3 times.
happy for you:smile:
Interesting, effects of gears used for test
would you mind displaying your final passing numbers?
Thx spooler
How do you retard the timing on an nsx?

1991 requirements
Emission laws are most likely written around model years without regard to what's actually under the hood. A 2000 vehicle will have stricter requirements than a 1990 vehicle. Manufacturers are free to use the same engine over multiple years as long as they meet the requirements for each year. The requirements for a given vehicle do change over time too, meaning that emissions numbers that get your 94 to pass this year might not make the grade next year.Passed today no problem.
But can anyone tell me why the same exact engine and emissions equip has different standards for different years? Just look at the 91 test, then the 94 standards?
Just seems lame to me, asking the same engine to meet different standards depending on the year it was produced.
If I am wrong, can someone point out the changes Honda made in emissions equipment from 1991 to 1994 on the NSX?
Thanks

Guys... need a little help
My smog failed again today... NO is higher than the max.
The tech told me to drive it for a month (since I don't drive it too much now) and said that it should do the trick. It didn't..the numbers today were similiar to attached. I don't have a printout of todays as he did a test without logging in the info as a favor for me. I added a bottle of Octane and ran fuel injection cleaner on my previous tank of gas.
I may try the O2 sensors and cleaning the EGR next.
I didn't notice what gears he was in... i think it was 1st and 2nd judging from the sound of the exhaust.
I removed the EGR valve earlier and did a good cleaning.... i'm gunna try to get it smogged again tomorrow to see if that was the issue.... :frown:
Make sure you clean the EGR pipes also. Get a good flexible wire brush and soak the EGR pipe and EGR in Seafoam.
Cleaning the EGR pipe and EGR made a hug difference in smog for me. I went from 800 NO to less than 100.
