you have to get a reading of the on board diagnostic system, Autozone read it for free . then they will print a code for you that will show which part is causing the problem (oxygen sensor or the catalytic converter )

There is a leak in the gas tank vapor system. Most of the time it is the gas cap but can be a hole in the tank, filler neck, or lines to the motor, not the gas hose but the vapor hose.
Evaporative Emission Control System Leak Detected (no purge flow
or large leak)
What does that mean?
This indicates a fuel vapor leak or lack of purge flow in the EVAP control
system. It means a large leak has been detected. The (EVAP) emission control

engine is running a purge control valve opens allowing intake vacuum to siphon
the fuel vapors into the engine.
