of those possible causes, i have a feeling its the ignition timing. it was tuned and chipped prior to me buying it- he kept the chipped ECU. Well, tomarrow, i'm gonna check the things you said, replace the cat, and losen to bolts to my muffler

gee, i sure hope exhaust doesn't leak out before the muffler [/sarcasm]

Hello I'm new to this forum blah blah blah. I have a swap honda blah blah blah.
Anyway, to pass you can simply park nearby the smog place. Turn the car off put a jumper in your ecu and turn it on. Then you can retard your timing on your dizzy from this point on. Turn the car off and remove the ecu jumper. The car might run a bit slower, but it will pass. Set your timing back after you finish the test the same way you set it before.. I had to do this on my civic and it passed like a ****.
I hope this helps.

That won't work. My old EF had a decent sized exhaust leak, and the sniffer wouldn't get a proper reading, so they had to rev it up higher to get a reading, which brought emissions up and failing it.

It worked for my camaro. I put I high flow cat on and never hooked the smog pump back up and i just hooked a cherry bomb on the back to have a full exhaust it leaked like crazy and I passed with flying colors

AFTERMATH:
Passed - by a whole lot

now putting out 96 HC PPM in idle, as opposed to 245 :P

Solutions: Cat w/ 1000 miles on it
Retarded ignition 8*.. know why? cuz it was advanced 8*!!

I got the idea from a HT member, who said he worked at an emissions place. told me to check my ignition timing, and since i knew it was tuned on a different ECU before, i knew that had to be it. Hooked up the lil light gun, and what do you know, its 8* advance.

so now its back to 0-1* advance, only because it wont go retard. now i can actually feel my vtak y0!

good work!

Must suck to have emissions. I did them once when I was 16, then MN stopped testing, and the cops don't know ---- so they wouldn't know that a honda isn't a factory turbo car.
