Well I have been having problems with inspection, I am not able to pass the emissions test. I have changed my oil, put a new fuel filter on, cleaned up the spark plugs and have also put a SMS catalytic convertor on my DC jdm header and T1R exhaust, that was running a test pipe before. The mods on my ITR are; Jdm Dc header, T1R exhaust, Skunk2 Cam gears(not tuned), aem fuel rail and intake. The hydrocarbns were at an astounding 728 and the co% were 9.13 . That is just two outrragous numbers and I have no idea why?!? I do have the CEL on, which is code number 54 which is CKF Sensor defective circuit. I dont see how this is because I have put a new one on recently and I even tried the little trick that you can do to make it think is works and I still have a CEL. Could it be my distributor? I just dont know what else could make me run soo rich. I am going to get my car tuned a soon as the new Neptune hardware is releaased but until then I needdd to pass emissions. Anyone know what could it be? Hopefully someone can chime in and help me out with this one. Thanks a lot!

 

Here's a picture for your viewing pleasures
Just one of my favorites from honda-tech.

 

pleasee helpp

 

what style header is it. i think if its 4-1 it wont pass. i tried to pass smog with a jdm oem 4-1 header and failed. i used my friends 4-2-1 header and passed on that try.

 

I do have 4-1 header i dont see why that would be a problem how many points did u drop on the test by switching headers? Anyone else?

 

dunno how many points but the techs at the shop said the exhaust flow is too high. i dunno, californias smog laws are gay. also, i had to use the stock piping, i was using 2.5" and swithed it out with the oem one.

 

Well can anyone help me out with my CEL i dont know what to do about it and it is bugging the hell out of me and I think it might be causing me to run rich too.

 

disconnect your negative battery terminal for about a minute. sometimes that resets the CEL. it worked for me in an em2 civic before.

 

damn, those numbers are really high. i'm a smog tech in nevada and our limit on 81 and newer vehicles is 220 HC and 1.20% CO. simply put you are running overly rich at idle (high CO indicates that) causing you to have a misfire and spit unburnt fuel out the exhaust (HC indicate that.) see if you can borrow a wideband o2 sensor and see what your a/f at idle is. code 54 might put it in a limp mode of sorts. hope this info helps.

I could possible get one but it would be from a GSR, is that ok?

 

probaby a bad cat or the 4-1.

 

do you have a adj fpr?

 

im running a 4-1 2.5" header with a 2.5" carsound cat/ spoon n1 catback and my car passes smog at near 0 on both HC and monoxide so i dont think either of those is your issue

im also running a chipped p28 and pass no problem what so ever......... however i do have a vafc and have tuned it so i bet your problem is in the fuel at idle........ mine is idling in the 15:1 area

I believe its that too but i dont know how it could be like that though, I have done nothing with the fuel, I use ti have a vafc but got rid of it a year ago. Im thinking that the CEL code 54 might have put my car in "limp mode" but my car still can be ran through vtec with no problems, so i dont know. Will a GSR distributor work on my ITR or will the timing be different? thanks

 

If your car is running really rich it can go bad in a month or so, Happened on my R twice.

Well I have only driven it once(to go to the dmv) since I put the cat on. Im not trying to drive it until i fgure out what to do.

 

Then that's not the problem. GL in fixing it!

 

like i said before, get a wideband on that bitch!!!! and then tune your idle accordingly.

the fact of the matter is, according to your numbers, is TOO MUCH FUEL AT IDLE!!

No one around here has one, I think im going to try and get a Vafc from a friend and just tune from that. Hopefully it will workk.

 

Anyone think a Vafc will help me out?

 

anyone??
