Wish Me Luck I'm doing My Smog Test Today

[88Accord-DX]

How is the EGR, replace it or just clean it out? Replacing the O2 sensor(s) might cure the rich A/F issue. Make sure your manifold vacuum is at 20 inches. MAP sensor voltages are less than 1.0 volt when the engine is idling at sea level. If the MAP sensor voltage is higher than 1.0 volt, the engine has low manifold that will result in a rich mixture.
Fuel injectors- Connect a fuel pressure gauge, start the engine. Turn off the engine, slowly & carefully pinch the return hose, & check the fuel pressure leak down rate. If the fuel pressure decreases more than 10 psi in 30 minutes, an injector is leaking causing a rich mixture.
Catalytic Converter- Since your in California, you'll need good catalyst. You'll need a monolithic one, which is coated with catalyst agent on a ceramic honeycomb material. If your talking about a high flow cat you get off ebay, that is basically a glorified test pipe.

EGR and injectors are new.
I'll still check on the injectors I may of gotten a bad one or more.
I'll be sure to check everything you mentioned and as far as the cat. I plan on getting either a stock replacement or high flow Magnaflow.
Thanks for pointing me in the right direction on where to start

[snoopyloopy]

failed on CO level

Readings were
15 mph Max .078 / Avg .010 / Meas 1.53
25 mph Max .066 / Avg .009 / Meas 1.64
Can someone tell me what the hell it means

Luckily the test only station was a friend of a friend and all he did was run it to see if it would pass or not. I should of mention that earlier that the results did not get sent to DMV

hmm...high carbon monoxide levels. if i'm not mistaken, i think that means low combustion temperature = running rich.

are you using the 4th gen map sensor pico?

[MessyHonda]

now that's bs. i still think the point of a smog test is lost when you can pass the sniffer but fail a visual. the air quality will suck whether or not the hoses are connected, but as long as it blows clean, it shouldn't matter. i think the carb needs to get off their high horses and realize that. </rant>

yeah the Motherfucker just raped me out of 40 extra bucks to retest my car. I hate lame mechanics thats why i never let anyone work on my car besides fam and friends.

yeah he is....pico change it to the stock one.

15 and 25 mph High CO readings , means too much unburned fuel at very little throttle opening just off idle. Problably not a whole lot of rpms involved ... then going by the lower CO reading it appears to clear out some. I assume it was with in specs at other speeds and such? As long as your MAF if at the correct idle reading (at or better less than 1) and you do not have a hesitation problem under any conditions, you should be alright with the curent 4gen. Just dont do too many things to it at once, it could make it worse, and you wont never know which one fixed it. I would try the free or little expense items first and borrow you buddys sniffer CO meter.
No idle problems right??


or just do the parakeet test. get you a couple parakeets put the cage behind the car, if sings you are ok, if it sleeps you got work to do.. Just kidding

[frantik]

lol roodoo for a sec i thought u were serious bout the birds i was like

[2oodoor]

of course I am kidding
I have heard of that sort of thing happening if you have Carbon Monoxide or Gas leaks in homes.

I put the stock one back in for the test

yes, all other speeds were within specs, as fas as my idle thats fine also

california sucks

[4ws90siky]

im glad i live in ky we dont have to worry bout that shit here. i guess thats about the only good thing about livn here lol..

[hanginbyaccord]

we dont have it here either , thank god.

[frantik]

california sucks

for smog, yes.. for everthing else, no

[cubert]

california sucks

where is you'r cam gear set at?
hopfully -0- and you'r timming is set at factory spec right.
high CO usaly means that timming is off. that would be a good place to start.

timing is at zero, a friend of mine suggested retarding the timing

cam gear timing is at zero right...
if you are running rich, retarding the timing will lean it out but dont retard it too much.

[tuxdreamerx]

damn im glad they took away our emissions tests because I have no cat lol. I can do wahtever I want to my car without worrying about emissions.

how old is your distributor?
You may have to rebuild it with new springs.
How long has it been since you did your tune up?
How big is your spark plug gap?
What kind coil do you have?
What kind wires do you have?

1) Dist. is original to the car
2) Tune-Up done when I rebuilt the engine March 07
3) Plug Gap .032
4) Coil= MSD Blaster II
5) wires = NGK

I just replaced the 02 sensors and had a friends shop run a check on it for me and the C0 levels went down a bit but not much.
I'm going to replace my MAP sensor with one that I had in the A/T vac.box and see if that helps and going to swap the ecu back to the A/T one that I had before when the car was auto and see if that does anything.
One thing I have that is not stock to the car is the injectors, they are off a 90 accord, how much of a difference would that be?
Oh well if the other stuff I mentioned above doesnt help any I'l go for the cat. which I suspect is the reason for the high C0. I took it off the donor car, it looked alright but I had my doubts before installing it but I had no choice and funds to replace it with a new one.

Probably the only difference in 90 Accord injectors would be the flow rate. (if there is a difference) I'm pretty sure a new cat would bright it back down to a passing level. One other trick that might help is to clean the IAT sensor. If you got some BrakeKleen, put the red stick on the end of the can & spray it for a second. Let it air dry & put it back on.

[Pico]

I'll give it a try

When i lived in texas i had a fiero gt with a s**t engine. i knew it wouldn't pass a sniff test so i put a bottle of "smog pass" in the tank. when they did the test it came out 0.001 or something like that (really low). Then again, the dual exhaust was rusted through on both sides between the muffler and tips. maybe thats what did it.
I'm a little sceptical as to if that stuff really works, but maybe you can have someone send you some if its illegal in cali.
