my smog thread

[UrDoneSRH]

basically to pass the guy said i need either a stock header/downpipe or a carb legal one... im not gonna fork over the $$$ for a dc header when im selling the car anyways.. and i have a high flow cat... its not a gutted cat or a test pipe.. but i just barely didnt pass the emissions portion.

so i pretty much just need the stock stuff if anyone has it. i can get a cat here, but if i can get a stock one with the downpipe and header id be stoked. i need to get it done asap too. so if anyone has it id be extremely happy to take it off your hands!

so basically, you just need a smog to sell your car right?? not for your exhaust ticket. anyhow, I'll check to see is I have one. if I do though, it'll be for the f22a1 though. meaning the hole for the O2 is gonna be at the bottom of the manifold. not on the a pipe.

[UrDoneSRH]

no i need it to clear the ticket, but i am also selling my car, thats why i was so pissed when i got the ticket, i had just put it up for sale!

i dont care what its for ill extend the wires if i gotta. i just gotta this handled so i can sell the cb and get my new car

[jhondayaaj]

how can you tell the difference between a high flow cat from a non factory one?? hopefully you didn't tell them that it was a high flow cat. because test pipes can be mistaken for a high flow cat. I'm assuming your high flow cat had the honey comb in it. I could possibly help you out on the exhaust manifold part and the a pipe. is your car an lx or a ex? thanks bro.

my friend john (new owner of 2.2litrebeater's ride) has just failed smog on his BAR'd JDM H22. everything else passed except for the HC's at 15mph. at 25mph it passed.

HC (PPM) max:116 ave:31 meas:~125 (close!)

the tech said there is too much unburnt gas causing the high HCs. he suggested to check the air filter to help get the combustion hotter. the car does have a full aluminum radiator and he only drove the car from cold to the station in 10mins. not adequately warm enough maybe? we'll be changing the plugs, getting a new filter, and retesting.

[2.2litrebeater]

the plugs should be fine but wouldnt hurt to swap em i guess, however that filter is definatly dirty.
also that magnaflow cat doesnt like to warm up, youre going to have to mash on it for more than 10 minutes and when you get to the station keep the car running. do both of those things and im sure itll pass since its so close as is. good luck

[jhondayaaj]

valve adj. wouldn't hurt wither.

good call, i never did that

[timmy0tool]

you wanna help me with the valve adjustment joesue? i have the feeler gauges, i just don't know how to "feel" them LOL.

yeah gary drove like a woman.. so new spark plugs wouldn't hurt..

H22's a bitch compared to the F22

[timmy0tool]

yeah he's having it done at the shop where they're doing his timing belt. i don't wanna mess with it myself.

[avitar110]

YES!, I passed smog today. I was hoping I wouldn't have to go to round 3!


Here are the initial #'s from Gary's last smog:

15mph test:
HC (PPM) max:118 meas:117 Close
CO(%) max:0.75 meas:0.21
NO (PPM) max:799 meas:123

25mph test:
HC (PPM) max:93 meas:60
CO(%) max:0.63 meas:0.13
NO (PPM) max:738 meas:52


My first smog attempt:
Adjusted timing and cleaned EGR port. (Did not warm up the car enough, drove for less then 10 mins!)

15mph test:
HC (PPM) max:118 meas:126 FAIL
CO(%) max:0.75 meas:0.25
NO (PPM) max:799 meas:185

25mph test:
HC (PPM) max:93 meas:78
CO(%) max:0.63 meas:0.13
NO (PPM) max:738 meas:87


My second and final attempt:
Changed air filter, spark plugs, adjusted timing, and adjusted valves. (Drove for at least 20 mins on the freeway at 80mph.)

15mph test:
HC (PPM) max:118 meas:117 Close
CO(%) max:0.75 meas:0.21
NO (PPM) max:799 meas:254

25mph test:
HC (PPM) max:93 meas:77
CO(%) max:0.63 meas:0.36
NO (PPM) max:738 meas:118


I'm glad I got this over with and can now get my registration!


After talking to the tech, he explained to me a few things:
The cat is responsible for your HC and CO #'s. He said to make sure that the car is hot enough, as it will help bring those #'s down. He also mentioned something about the temperture of the car and how the thermostat is affected, and yada yada yada, but by that point, I was tuning him out as I was ecstatic to have passed smog.

Spark plugs has the biggest affect on HC #'s. Example, hot vs. cold, and gapping! He said the first place you should check if that is the only measure barely over the limit is the plugs, as I was in this case. Clean air filters, adjusting timing, valve adjustments, etc. should be considered next. If your HC #'s are high, there is too much unburnt fuel.

Faulty O2 sensor affects your CO(%).

Low CO(%) and high NO #'s mean your leaning out, and there is not enough fuel.

And we all know that a dirty or defective egr will cause you to have high NO #'s.

I'm just happy to have passed smog!
