What does it smell like? Could be a CAT going bad or running rich... Oil or coolant leak... Clutch burning - which is worst than the smell of death.

Running pig rich will make your exhaust smell like rotten eggs because of the extra sulphur.

An o2 sensor malfunction/ failure can cause the symptoms you are indeed having. Replace the sensor before real damage occurs
