I did several smoke tests, I replaced the gas cap, the purge valve and the vent valve and drove it over 120 miles in 3 days with the hopes that the computer decides that the small leak was fixed and turned off my check engine light, but the check engine light is still on. So I was just about to give up and take it to a shop. Today I went to Advance Auto Parts and ask the guy there to do another reading of my error code to make sure that it is still the same and to my surprise he told me that the computer WILL NOT TURN OFF the check engine light, even if the problem has been fixed. Now that would be horrible. IS THAT TRUE? He said that the only way this check engine light goes away is by resetting it, which he did. Now let'* see if the light comes back. This problem may have been fixed weeks ago unbeknownst to me thinking the light goes out when it'* fixed

It should go out on its own, but after several drive cycles. Perhaps you didn't have enough cycles for it to reset itself yet. For clarity: You can get in and drive 300 miles in a drive cycle, and it will be one cycle.

Here is how it ends. On my last post I said that I did an extensive smoke test and all the lines seemed to check out fine. I replaced the purge valve, the vent valve and the gas cap, had the code cleared at a Advanced Auto parts store, driven the car almost 1300 miles in the last 1 1/2 months and the check engine light stays gone. So I count my blessings and keep my fingers crossed. The light may come on again in one of these days or it may not, but so far it appears that the problem has been fixed. Thanks y'all for your help, advise and good ideas.

Cool!

Thanks for letting us know how it turned out!
