Replaced the evap canister and still getting these two codes every few days after I reset them with the scanner, my guess is everytime a drive cycle is complete they come back on. Replacing the gas cap tonight, which would have been the faster and easier fix but apparently thats not me. Any other ideas? I know the 4055 is the evap leak code but what is the 4096?? Looked all over the internet, even searched on here and couldn't find it.
