Yeah the CO is waaaay over, normally just overfuelling but there are hundreds of causes, few to check. Fucked o2 sensor Restricted air filter Vac leaks to MAP sensor (car would barely run) Fucked cat or not up to temp Carbon canister fuel vapour system inop Fuel / oil contaminated together Or just not changing oil frequently Thermostat stuck wide open Thats concentrating on the CO related things. Hope this helps somewhat buddy and keep us up to date with how you get on
