so i went to the ref passed all visual but fail the
15 mph :hc 88/103 and no 704/713 <can i run that guranteed to pass juice and lower these numbers? 25mph i passed all so ya whats the best thing i can do? my timing was 18 btdc if i move to 20 or 22 can i lower these number enough to pass?

the repairs ive done
new oem o2 ,oem egr valve,oem egr solenoid,all vac lines changed,new plugs and wires ONLY THING I HAVENT CHANGED WAS CAT, BUT I PASS SMOG COUPLE MONTHS AGO if i have a messed up cat wouldnt i fail across the board ?

SOHC KA = 15 degree

DOHC KA = 20 degree

that should help the numbers...

miklos · 10-22-2009, 05:29 AM

Found out the EGR solenoid had no ground. The manifold passage was filled with carbon where the EGR mounts. The Vacuum lines were melted back there on an SOHC.
And the egr carbon was there after running seafoam through the throttle body twice.

BILLFISHER21 · 10-22-2009, 08:47 AM

im so happy we dont have emissions in fl

u want a grantee pass, change ur oil, change filter change or clean o2 and plugs...and check if CAT is good

blackrms13 · 10-28-2009, 03:55 PM

those bottle of guarantee to pass thing did not work for me...
then again my numbers were like 3000+ for NOx...so yeah

cc4usmc · 10-29-2009, 05:29 PM

How does a smog tech determine that there's a split in a pcv breather hose? I just yanked mine out and cleaned it up and there's no split...and these aren't flimsy little hoses either.

Edit- Is it possible I pulled the wrong hose? I pulled the one coming directly from the pcv. I did a lot of searching but could only come up with threads with dead pictures. When I called the Nissan dealership the guy I spoke to said there are two hoses....so... fuck.

Prime · 10-29-2009, 06:08 PM

If you're still answering questions... and don't mind?

High HC @ idle, I don't have to roll just run at idle and I think 2500rpm. Everything else checks super clean. I'm at work and don't have the sheet in front of me atm, so just ideas would help a lot. New o2, new plugs, wires, oil change, fuel filter, 1 yr/o CAT, 91 KA24DE in a 90 chassis, timing 20DBTDC.

stinky_180 · 10-29-2009, 06:22 PM

my friend was wondering if you can pass smog with a 3" catback exhaust......

completely stock and everything

read my first post i only failed 15 mph not by that much if i had a bad cat would i have failed at the 25 mph as well and on top of all of my emission required equipment has been change not to long ago 5 months give or take 1 or 2 months i have a dirty ass filter lol

RBD240 · 10-30-2009, 05:01 PM

Man, i am glad i live in oregon. In a town that has no smog or deq, My rb20 with 3 inch all the way back and no cat would definatly not pass.

My suggestion to all is move. haha

Goodluck to all. sounds like it sucks.

LB.Motoring · 10-30-2009, 05:09 PM

I throw a code because of a wheel sensor, could I clear it drive it around then pass smog?

TurboStrong · 11-01-2009, 06:03 PM

hey i was just wondering whats good oil pressure for a s14 sr20det?

SmogSUX · 11-06-2009, 07:50 PM

BAR told me just come to the referee & they will approve it since it is newer than what came in the 89.

s13love-green · 11-07-2009, 11:36 PM

hey so will it pass if i swapped sohc to dohc????

If your motor can pass smog, the BAR should give you a sticker or plaque saying that your swap is legal since ithe motor is newer than what originally came in your chassis.

s13love-green · 11-08-2009, 11:08 AM

do u guys pass cars ...for example i know my wont pass visial so can i take a car same yea and model as a sub to pass mine????

articdragon192 · 11-08-2009, 12:35 PM

I really don't think that's the point of this thread.

S-Nation S13 · 11-09-2009, 10:45 AM

had a question, what causes you to fail on low speed hc/nox but not high speed. ive cleaned my air filter/check my plugs/timing/clean throttle plate/had all emission related units changed with oem nissan parts/ cat is still the same "IF I HAD A BAD CAT I KNOW FOR SURE ID FAIL HIGH SPEED AND I WOULD FAILL ALL ACROSS THE BOARD!!!"

S-Nation S13 · 11-10-2009, 03:46 PM

so i went back to the ref here are me results:
15mph: HC 88/137 CO 0.52/0.06 NO 704/594
25mph: HC 53/53 CO 0.50/0.06 NO 738/530

ive changed everything possible cap n rotor are next as well as new ngk iridiums and wires, is there anything i can do to lower hc only? ive heard of rubbing alcohol ? is this true?

Howlermonkey · 11-10-2009, 07:29 PM

In virginia, they use the standards for the newer motor if it's in an older car.

If the car is newer than the motor, they use the car standards.

Of course, the tech. would first have to recognize that the car had a different year motor.

S-Nation S13 · 11-12-2009, 01:40 PM

anyone anyone????? well today just changed out cap and rotor as well as plug wires,oil change and oil filter currently im going to re-time my ignition , any more things i can do to lower my HC readings?????? please im in need of my car lol its the only transportation i have so any help will do please!!

Dezi · 11-13-2009, 02:34 PM

Emissions seem to be a big deal in California but I was wondering if anyone from Florida knows the local laws on emissions or if we are required to get a smog test at all. Another thing I would like to know is if I had a car brought to Florida from another state does it have to get a smog test before I can register it in Florida?

pcv hose is the big one coming out of the valve cover. yes, THAT big one. it goes into the intake, just before the throttle body on a dohc

a cat will drop your emissions across the board. youre still measuring high for HC and NOX. granted you are passing the 25mph, the numbers are still high. if your timing, and smog equipment is on the dot, the only thing i could think of would be a misfire, or the cat might actually be bad. is there high O2 coming out as well?
