I have these three codes. I checked gas cap for a good seal and also get the check gas cap message. I am thinking about changing the purge solenoid. Check engine light comes on and goes out intermittent. Any ideas?

You have a vacuum leak or you are correct that the purge is the issue. However, I have attached the info we need to do through in order to figure out what we need to replace.

Here is a guide that will get you some more info on the P0171:

The P0497 is the code we need to run through to determine this. I attached all the info needed to figure this out. Please let me know what questions you have. Don't worry about using the specific tool they are using. We just need to use a vacuum gauge. Thanks

I changed the gas cap and the Evap Purge valve. I cleared all of the codes and the codes have not returned. Even the P0171 code has not returned. The other two codes definitely have not returned. Also the check gas cap warning on the dash cluster has gone away. Thanks for your help.
