2004 impala 66,000 miles 6 cylinder

My engine light keeps coming on. I replaced the gas cap. I had auto zone run the codes and they said I had a leak?? They reset it after I replaced the gas cap and within 4 days it is back on. What else could it be?

The evaporative system has various components that may be failing. However it may also be a simple as a hose that has become disconnected or leaking. There may be a valve stcking or the neck leaking. The car needs to go to a shop that is current with the techniques of diagnosing this code. It may involve injecting smoke into the system or using a scanner capable of remotely controling the valves associated with the evaporative system.
