i have a 3rd gen ram 4.7 once in a while itl bog out or even stall not very frequent but still does however it very very rarely does it more than once in a day i also keep getting a 456(small evap leak code) wich people say it is gas cap how can i tell if the cap is bad?

i had the same problem i tighted the gas cap and erased the error and havent had anything but same thing happened to me

i did the same thing but it would come back say a month and a half later same code so i guess i gotta get a new cap you knopw? start cheap i guess does your cap have alot of play in it?

Check your eval canister, mine was broken and was getting the same code. Jb welded it back together and haven't had a code sense.

i am waiting for it to happen again and ill do ^^^^ that if anything but i know some places do the smoke testing and it can find a leak if anything

its in a dealership or a good shop im not sure my gas cap feels lose P.S mine just did it again just not staling but the light came on and it had the same thing
