      '07 Aveo Sedan idle's high on startup

      Every time I start my car, it idles unusually high at about 1500 RPMS for maybe 15 seconds. Then, it goes back down to normal idle, ~900-1000. It's enough to be annoying, but it goes away without any user input. Ideas?

      It has to do this you can't mess with the car until it idles down or risk damaging the engine.

      mine will idle high for 10 seconds or so (1500), then go sit right on 1000 for another 10 seconds, then idle normally, it feels wired, but it is normal

      Mine went from 3-4 seconds to 6-10 seconds when I removed my cat.

      In the US it is illegal to remove the Catalytic Converter, because it is made of Platinum and metal recyclers have a new policy when receiving them A two week Holding period to make sure the Cat is not stolen.

      So just because it's made of Platinum it makes it illegal to remove it?

      And what exactly do the metal recyclers do in those two weeks to check if the converter is not stolen? Keep in mind that converters to this date are not serialized parts, at least not to my knowledge that is.

      Check this link out,

      from what it sounds like, the laws will take a while to take effect, if they ever will, and they're not nationwide, they're state specific... And it varies greatly, from 3 day tag-and-hold in some states to 2 years of records in others. And I couldn't find Washington state in there...

      And to my knowledge, there is no emissions testing in many Eastern Washington counties and many Western Washington counties outside of major metropolitan areas of Seattle, Tacoma, and possibly Olympia (not sure, XJCasper would know better).

      And if we're talking about the legal side of things, any tampering with emission system is illegal for that matter...

      And for the record, I can neither confirm nor deny that my cat was removed temporarily for the purpose of checking the exhaust system for leaks and malfunctions. :-" The ECU tells me that the cat is working properly by not giving me any codes...

      its not illegal because it is made of platinum. Its illegal because of federal emissions laws, its worded something like: you may not remove a functional (working, not clogged or damaged) cat from you vehicle.

      thats about it.. i bet even without the cat his aveo produces less emissions and uses less gas driving 50 miles than a v10 excursion driving the same distance. this is where i think the laws need rethought.

      You'd be wrong... although carbon dioxide emissions will be fine without the cat. It's the NOx and Hydrocarbon emissions that get a treatment in the cat. If you remove the cat, the hydrocarbon emissions go through the roof and that's why the exhaust smells like gasoline... NOx contributes to global warming, acid rain and smog.
