many thanks for your help -- i understand the 1443 code points one towards an issue in/with the evaporative emission control system -- what i can't figure out is which component to replace -- there seems to be a EVAP purge flow sensor and a vapor canister purge valve -- but every parts site i have looked is not all that definitive about what to replace -- and many were not specific to a cobra -- appreciate any direction / suggestions you might offer --
