Could use some help here. Failed emissions but not sure what to try and fix.

I have no codes.

40KM

HC - Limit: 78 - My Reading: 263 - FAIL

Are they basing the numbers on the right engine. make sure that they went as hot rod and not stock ef motor

Yeah man and if it still fails try some methly hydrate u can get it at napa Kleen flo makes it an it comes in 1L red containers I failed my etest with close numbers to urs man ran $5 high test from an empty tank and only 1L of this some people suggest upto 4 but i dont think that is safe an i passed with flying colours man just my .02 hope it works out for you buddy, goodluck

Neil hotrod can only done if the displacement is larger. Unless his model came with a 1.5L he cant do a hotrod test.

BOND007

THE STOCK ENGINE on an 89 si would be of smalled displacement then a b16

chris_si98

last time I checked a d16a6 was a 1.6L

imported_Joe_98Si

^^word, both are 1.6L

BOND007

You are telling me that the displament in that single overhead cam engine would be more than the displacement on a double

Cynikal.Mindset

the dohc is like 1cc larger than the sohc if that...just one has 2 cams and the other has 1 cam

chris_si98

I didn't say more.

They are both classified as 1.6L's.

BOND007

but one is still bigger

chris_si98

so? You still can't classify it as a hotrod test.

Jayamashey

They are both 1.6L so unable to test as a hotrod. Any other suggestions as to why its not buring all the fuel?

Cynikal.Mindset

iridium plugs and nology wires would be my guess...put in some correct plugs and some normal wires...hell do a cap and rotor too

i find those iridium plugs to be junk

BOND007

So does that mean that on my ek d16y7 i would not have to say anything about change to b16

chris_si98

That is correct.

BOND007

i hope i pass this year then ....

by high test do you mean 91 octane or something? because running higher octane will make your results worse.. if high test doesnt mean high octane then never mind what i just wrote.

Jayamashey

Well - just had my timing checked from a friend at Honda and it was off 6 degrees advanced. Hoping that solves the problem. Shouldn't be the plugs or the wires.

iwanna93sihatch

no it wont man mine failed an yes u ran 91 octane which runs hotter an the cat was hotter an it brunt the gasses better i guess and I used 1 litre of kleen flo methyl hydrate and passed with flying colours the next day
