This could be anything in the SAI system. Start with verifying that the air pump is turning on during cold starts. Next, check the changeover valve since it's easy to get to. After that, I'd check for vacuum leaks. Moving down the line, check the electronic changeover valve and check valve (alternator must be removed to get to them - depending on the year of your car, you may have a combination valve that has both the changeover and check valve in one unit).
