failed emissions testing - no codes. Test results showed that the oxygen sensors were not ready. The tester said to ride it for a while and try again. Bad luck. The sensors sometimes acted somewhat incorrectly. The dealer did not provide any information. Finally some said check this article and where it is. I did == ah ha, found a big hole rusted in the back, everything looked fine inside, but then I saw there was a small wire about 6 inches from the connector. I plugged it back in, drove around the block twice and plugged in my code reader and it finally said the oxygen sensors were ready for testing. I go to the inspection station, they plug it in and BOOM it passes! :) I siliconized the shit on the back and covered it with plastic to make it waterproof. It's been a year now and everything is fine. Hope that helps.
