SO.. wtf? How do i fix that. It does idle at like 800 like a good little honda, and it produces no visable emissions except when cold

And, I don't know if it makes a difference, but for the car info, its a SEDAN, and a 1.5 liter.. which is incorrect. Stock is 1.6L, and its a Hatchback, not a 4 door POS..

Help appreciated. I definately need to get this bitch passed, registered, insured, before Friday.. for our local "High School Drags" event at a local raceway

so they are testing your gsr motor against a d15b7? not sure how it is up there, but in cali, you are supposed to register the new engine with you car. and when they test it, it will be against the car the new motor came from. but only 2% of the people do that.
sorry man.

yeah telling us where you live will help

make sure it goes in nice and warm! if its failing hydroCarbons isn;'t that a sign of a failing CAT?

That was what i thought. New cat should fix it.

when i smogged in my 94 civic DX, with a b16 (just an intake and exhaust) i failed, not exactly sure but i think it was the cruise emissions, i went to shucks and bought the gauranteed to pass ----, ran it through a tank, filled up, and went back and passed... RAPE the ---- out of your car before you pull up, i was doing pulls in front of the place, haha. Also, if there is a long line, rev it to 3-4000 and let it sit there, or rev up and down (Josh Ross Trick, haha) they will look at you like your nuts, but a hot cat is a cleaner cat, but i passed when i went back.... -Zac

sorry bout that. Seattle, Washington.

the cat is probably still the original cat.. and i've got one from my old 94 civic 4door with about 1000 miles on it. just stopped making that clicking noise

i'll try that and go tomarrow

spoon fed

if you can, put a new cat in...but make sure that ---- is hot hot hot when you go in...take it for a good drive and just leave it running while its waiting to go in

run low octane gas, get the car hot, if that doesnt work, borrow an safc or vafc from a friend, install it an lean out te low rpms, I got a turbo b16 to pass as a 1.5l dpfi motor like that

Tatakai

yea.. my friend told me the high (pump) octane was better.. crackhead. i put that stuff in my motor anyway. maybe if i use the middle it would pass? cat is being installed tomarrow.. just got back from yanking it from the old civic

prior to testing, it had done some showing off (the swap was recent, so ppl are still oohing and awwing), drove 6 miles, with the last 2 on the freeway. so it was pretty hot. although, i sat at a red light just before, and waited in line probably 10 minutes after i arrived.. i'm gonna try revving to about 3K every once in a while im waiting in line.

well you have an hc problem an thats not cat realted......Hc is raw unburned fuel CO is partially unburned fuel
Cause of high hc are as follows
valves out of adjustment,
spark plug missfire due to wrong gap or defective plug.
Ignition timing off,
Leaky injector
head gasket seaping
low compression.

i would check those first.
You do have some high co at cruise so it is possible it is being over saturated
Just my 2 cents since i do the emmissions testing for peeps to get them to pass at my work.
