My neighbors got a CEL on light today, took it to autozone and we got p0455 on it, EVAP leak.
So, 420a, 99 on good condition but with a lifter tick... (i dunno what it is and if its relevant or not)
Evap canister leak right?
im replacing the fuel tank lid thingy tomorrow, and im also getting a in-engine bay vacuum meter to check on the vacuum to see if theres a leak somewhere there...
if by any chance none of these 2 solves that CEL what path should i take? help will be appreciated, were leaving for spring break in rosarito on friday =)

 

I believe the evap canister is below the battery tray, so i would start by looking at that. And then check the vaccuum lines going to that
