Failed emissions test with high CO - FIXED
Just thought I would post this here to help someone else out if you run into this. My 460 truck failed with high CO on the high-speed test, limit is 1.2 and I was at 2.2. High CO is caused by a rich mixture, so I replaced the O2 sensor just because I had one in my toolbox already. The CO dropped to 0.04, just got my sticker at lunchtime today.
