failed smog JDM B18C (GSR)
took to ref today.. failed the HC (PPM) at idle. Max is 100, Ave is 17, and mine (Meas) came out 131. everything else pass including 2500rpm, visual, functional. The notes says to Check/Repair high HC emissions...
now i have no clue on that. what do i need to adjust or fix?

I failed that today also. Where did you get your ref check at? High HC's usually means the fuel isnt burning effieciently enough and is spitting out the exhaust. Try checking the spark plugs and timing.

Re: (DelSolSiR)
spark plugs are good... timing is 15 as said on paper.
cat? dont know.. passed with civic motor last time. wouldnt it work again? would it have to do with idle high since mine is doing 850 rpm somewhere around there.
did mine at yuba college.

he passed visual, which means the ref already checked for a USDM ecu

Re: (sit220)
Do a tuneup and see if that helps any. I feel sorry for you guys, pretty much every time you see a thread about someone failing inspection you can almost count on opening the thread and seeing the original poster is from California.

i passed state ref with 91 octane. i dont think running 87 will help, even if just a bit, and even tho it might burn a little bit cleaner.

no. im using a jdm gsr also and passed with flying colors.
i changed my cat and got a new hi-flo magnaflow cat, cleaned o2 sensor with brake cleaner, changed plugs and oil, got a new oil pressure switch and housing, and installed an evap purge control solenoid valve = pass and BAR'd

I KNOW it will help. I have passed the ref before on cars I have worked on by switching the grade of fuel to 87. I'll put $20 on it that says he can pass with 87. Take me up on the offer?

Re: (Hybrid93Eg)
87 might help just a bit, but not without doing a bit of tune up along with it. cuz i tried 87 also on some info provided here on H-T. still failed. then i did wat i stated before and passed.
i really doubt 87 will flat out boom make u pass like that.

Re: (Hybrid93Eg)
Yes, try 87. Replace plugs (CHECK the gap), check timing (16*), and try again.
You'll pass. You're not that far off.. which is why downgrading octane should help in your case.

Well, he isn't THAT much off the limit... and you would be surprised how much of a difference it will make. Its not going to work wonders on a heap of ***... But the thing is he said it was the ONLY thing he failed was HC. HC = unburnt fuel. Plain and simple. If the cat was the problem, then it would have failed across the board, not just in HC. His car is not completely burning the fuel that its being given. Could need new plugs or have another ignition related problem and it could also be running rediculously rich at the same time. Notice he also failed the 15mph test, when the cat is cooler and the engine is under more of a load. Makes plenty of sense. Put the 87 in an I am willing to put $20 up with you that says it brings his levels low enough to pass. It might be a "Scrape by" pass, but it should pass none-the-less.

Re: failed smog JDM B18C (5lugcivic)
I go to NASCAR Tech at UTI and I am right now in class with fuel and emissions. High HC is a result of misfire. What was your CO readings and were these HCs getting better with RPM. If so its an ignition problem. If it got worse its a bad coil. If it stayed fairly the same its a mechanical problem.
