so im running rich on my emissions test
im going back tomorrow but recently since i failed i put some things back on to the car.
i put the stock cat back on, but still with the 2.5" piping, cherry bomb, to a n1
i also put a vafc in it also, can i lower the settings to make it run lean?
to pass it was 2.55 i think and i got a 4.78 so not by so much.
i put new spark plugs and wires. do u think if i lowered the settings will i be fine? or will i be fine now with the stock cat on?

mods: vafc, dc headers, intake, full exhaust, b16a

thanks

 

guess no help..thanks though

 

give it time, and those who know the answer shall post, bump for you and your failed emissions test

 

cool, but yay for me i just passed emissions with flying colors.. lol thanks though

 

How was the first result and after? I also need to pass the emission test this week. I changed my cat, spark plug, oil (it was black), exhaust and used "Guarantee to Pass Emission Test" with V POWER fuel from SHELL.

Go to home depot and by Denatured Alcohol, and by the way, V power is the best gas by shell right ? You want the lowest because its easier to burn.

 

well i re put the cat on and changed the plugs and wires.
changed oil n filter at work
before i went to emissions i was driving around for like a hour or so warming up the cat nice and hot. while i was waiting i had the car at 2grand till i was like 2 cars before my turn. was like 6 cars back. i put the vafc back to stock settings on the fuel system. and filled it up with circle k 89 gas full tank. lol

to pass it was a
12.00 i got a 1.39 thats for co
1.00 i got a 0.11 thats for hc
2.50 i got a 1.48 thats for nox

so i passed with flying colors

my previous scores were this
co 18.52 to pass was 12.00
hc 2.23 to pass was 1.00
nox 5.44 to pass was 2.50

so i guess the cat and new wires n plugs helped a lot, lol

 

Will my automotive teacher told me to get the best fuel to clean the injector and the vacuum.

Why do I need the Denatured Alcohol for?
