Found the codes and looked it up--"Evaporator Canister". Now trying out a exact copy of the gas cap and will disconnect the Positive cable for 30 minutes(?).
What is the exact code?
It most likely isn't the gas cap..
It is most likely an issue with the evap system although the cap becomes part of the evap system.
See THIS LINK for some of the possible codes for the evap system and some explanations..
Also , if you have a real code reader, you do not have to disconnect the battery to reset. You can use the reader to PROPERLY reset the lights (be aware in resetting the codes you may make diagnosing your problem harder since it will take multiple driving cycles to bring back any and all codes)..
Also removing the battery may not clear all codes (some codes can only be reset with a proper code reader) and on top of that your vehicle will need to relearn all the engine settings..
Engine light will most likely come back on in two or three driving cycles..
Check for any pending codes BEFORE resetting the check engine light and write all found codes down.. They will help pin point the problem.
