The best and first thing to do is to have a skilled technician scan the computer for trouble codes and to do a data stream evaluation of the engine sensors and actuators. Then have them do an exhaust back pressure test to determine if the catalytic converters are restricted or plugged up. Best of Luck!
it is the H02`s and the catalytic converters i had the same thing rong with my is300 it cost about $3600.00 to fix mine
