Help...Just had all 3 catalytic converters replace in 2007 Sante fe.1000 miles ago now im getting the same problem with car. It has error codes p0302--p0441--p2187---p2189---Can you give me an idea of what to check first...I'm on vacation and 500 mile from dealer who did it.
its possible there is an exhaust system leak, try to hear for exhaust leaks.
Check for gas cap to see if its on tight. and reset the codes (if you dont have an OBD-II reader disconnect the battery for 30min or so. also check for intake leaks, there might be a loose, cracked or borken hose by the engine bay. Good luck
