Question P0457 Gas Cap

Hey guys,
I'm getting this code and before I get a new cap, where is the evap box located so I can check the lines?
Also, the past two mornings I've been getting throttle lag in the exact same location driving to work. It's about 10 minutes into my drives and at low rpms I press the gas and it seems like the Jeep stutters a bit and doesn't want to go. It only happens a few times at the same stop. Lol anyway, it didn't do it this morning but I popped this code. Any supposed relation?

Hey mate
Have you found the solution?
I'm new here and seems the forum is not really active.

There is at least one other similar thread - but basically gas cap can be related to the cap not being on tight, a leak somewhere, or the evap box being full - not sure where the box is myself but have you checked your manual? on a 2007 model there should be a owners guide available after market that will help you check maintenance and location.

The evap box (charcoal canister) is located under the vehicle, left side, rear, behind the wheel.
