  • Failed CA smog: [email protected]

    Hi-

    I failed my first CA smog test and Juan at SBI suggested I post the numbers up here so he could take a look. So I don't think I'll need input unless you're so inclined.

    !5 MPH; 25MPH

    %CO2 MEAS 14.1; 14.3
    %O2 MEAS 0.2; 0.0

    HC (PPM) MAX 118; 93
    HC (PPM) AVE 31; 20
    HC (PPM) MEAS 51; 35

    CO% MAX 0.75; 0.63
    CO% AVE 0.10; 0.09
    CO% MEAS 0.13; 0.07

    NO (PPM) MAX 799; 738
    NO (PPM) AVE 237; 199
    NO (PPM) MEAS 894; 513 FAIL


    Relevant service history (current mileage 88,000):
    7/2002 62,631 distributor cap, rotor, ignition wires, air filter
    7/2003 65,517 adjust valves, throttle bodies, co, clean throttles
    4/2005 68,190 change fuel filter
    11/2006 72,689 replace thermostat
    6/2008 83,000 change spark plugs
    11/2008 87,450 replace oxygen sensor

    Relevant mods:
    Evo airbox
    Evo exhaust cam gear
    VSR center section
    Eisenmann muffler
    Barometric sensor disconnected
    usually run TMS chip, but replaced with stock chip for emissions test

    I think that's pretty much it, except that I've always thought it's run a little rich given soot on the back end. Any help appreciated.

    Thanks,
    Mark

    All I can add is that I passed my last california smog using my Turner chip. I just tuned the alpha N map to perfection.

      get the car much warmer. Try to get it on the rollers immediately.
      You can also try pulling one of the caps on the throttle bodies.(just one)-worked for me

      Good luck!

          Cats replaced with the center section about 23,000 miles/5 years ago.

            I just passed my Smog.. Barely!!!! I have turner chip with strumhong exhaust. I drove the car at above 6000 RPM for about 10-15 minutes and took it to the smog guy. luckily there were not many people there so he put it right away and I passed. you should run it hard to get the cat nice and hot, so it can work extra hard. luckily, this give me 2 years before I need to change my exhaust and cat.

              Your cat is still good. You're just running a little too lean. Either rich it up a little bit or warm up your cat a little bit more and you'll pass.

                Huge props to Juan at SBI who used fuel injector cleaner, richened it up a bit, and actually went to do the smog check with me! It passed, but barely. Still running lean.

                I highly recommend SBI for anybody near LA.

                        Yeah, I was wondering why a Vietnamese guy would be named Juan. But, hey, its LA so I didn't ask. Hoa rocks.

                          +1 for Hoa at SBI. He's an excellent tech and very trustworthy.

                          (His name is pronounced similar to "wah"--a note for the whiteboys like me )

                            Another plus for HOA and SBI, they've been working on my car for years now and I wouldn't take it anywhere else even though its 40 minutes away from me. These are the guys that make me want to drive a BMW forever.
