    Angry Burb fails smog check

    The burb failed its smog test yesterday. CO levels were a tad high. Took it to a test only station and besides the CO, the gas cap did not pass either. I thought I'd start with cleaning the K&N and a fresh set of plugs. Any suggestions?

    Did you drive it at least a half hour before the smog test was done?

    If you did not it may have still been in the start up mode. High fuel or whatever it’s called. I know when we lived in Taxachusetts if the vehicle wasn’t warmed up it would never pass.

    Try running some fuel injector cleaner/engine treatment through it. If you had failed on NOx then I would have suggested EGR or Cat, but CO just sounds like it is dirty somewhere. And as Fiero said, warm it up real nice. Good luck.

    Cool, I'll give it a try. Stay tuned for test#2 results.

    New plugs and air filter. Dumped a can of seafoam in the tank and going for a retest today. Plugs 1 & 3 showed signs of wear. Hope for the best.

    Good luck! Don't forget about 10 mile tour at freeway speeds then go right in to be tested. Don't shut it off when you get there.

    Failed test #2. The 1st tech was a tard! The second tech spotted it right away. Bad cat! Quoted $140 for a cat or $340 for cat and a cat back system with a Magnaflow and 3" pipe with the mandatory chrome tip. Went for the whole package and the 3rd test passed! Whoopee
    Sounds mellow enough too. Can't wait for the Cajon Pass climbing test to see if there are any extra benefits in the HP department.

    Plugged cat? Well I'll be damned. I'm surprised you didn't feel that earlier...? Anyway good for you, an unexpected upgrade.

    Cat wasn't plugged, just worn out. 240k and it was done. btw went to a test only station, so they weren't trying to sell me anything. Howard's Muffler quoted me a fair price and got the job done the same day!

    See, I told you so!! I have the Magnaflow catback on my 99 and love it. Nice mellow tone and a few more ponies pushing it.
