    Hey I read some comments that you guys have related to that topic and so far I went to get the codes to autozone and the ones that I got was po441 and po455 and both mentioned a possible cause might be a leak or failure on something call EVAC... What Is that???

    That is a vacuum related issue. Check all your hoses and intake to ensure that they are tight and secure. You may also have a hose/fitting or line that is failing due to a crack or puncture, which would need to be replaced.

    The gas caps have a rubber o-ring that dries out and cracks that causes a vacuum leak or poor seal, that was why you had the CEL.
