dorifito

hi i there any way to fix this problem with the EVAP? other then swap out the box under the car ? i have taken it out and and cleaned it and got a new gas cap and it worked out fine but now i noticed that i get no vacuum when i open the gas cap to put gas and if i don't close it really tight it will give me the check engine light. any ideas?

Gas cap or tank vaccuum has nothing to do with code P1457.
