Need more info. From what you posted I would suggest removing and cleaning the Master airflow sensor located about 6 inches from air filter. Need safety starheads to remove it. Otherwise, it could a fouled catalytic converter. But, need more info and get check engine code read if possible. Use master airflow cleaner only on the sensor.
