Do you have your HC numbers? How far off from the limit are you? To get my FJ40 to pass, I ended up taking it to a shop that had the emissions equipment and having them make the adjustments to get me through. In my case, they had to bump the idle up to 1200 rpm, which was pretty high as the limit was 1300. Even with the high idle, I barely squeaked by.
