Hi John Probably way off the mark here, but I would recheck the work that the previous workshop have done. I had a Voyager in recently that has 10% CO. Previous repairer had fitted a new cat & O2 sensor. The Muppet had replaced the downstream sensor with a Titania sensor (should have been a Zirconia type). Also the CTS value in live data was too random & not logging a DTC. HTH Dave (Hill)
