2006 Impala 3.5 evap delete has check gas cap warning

Hi all,

I have a 2006 Impala here i did an evap/cat delete on. I tuned all the codes out by setting then to #3 no error reported. Both evap and cat monitors show completed. After the vehicle is driven for a few days the "check gas cap" warning comes on in the dash. Any fix for this?

Thanks,

Anyone?

Post your file so we can look at the Dtcs

Here is the file

un-check all the ses enable box's for those codes.

Thanks. I will give that a shot. I always did them with the boxes left checked but i have not done 1 with a DIC that displays messages.
