Just as the title says, '02 stratus with these codes but it runs fine. The gas cap was a little loose but want to make sure it's not some time more.
What are these codes, didn 't get much from google or this forum search. Thanks in advance.

 

looks like 1684 just means the battery was disconnected or the PCM lost its power.... the other i think is a fuel evap leak or the loose gas cap

 

Not gas cap the light is still on, topped it of with gas this morning as well.

 

I believe you have to reset the PCM... a scanner or disconnect the battery for awhile
