Hello, I'm new here and a proud owner of a new/used 1993 Toyota Land Cruiser. I bought it a week ago and decided to take it in to get it smog so I can get the sticker for it. I took it on the highway ran it for 10 min before going to get tested, looks like everything passed except there's to much CO% when its idling. See picture attached of the test result and let me know what your suggestion are. Thank you
