Just figured i would post this as an FYI

My wife said that the car is rough starting after filling up with gas. Also a check engine light came on for a P0456.

I thought maybe the capless fuel filler and cleaned that and sprayed a bit of silicon on the emergency filler tube then proceeded to insert it into the filler neck a bunch of times. Hopefully my neighbors werent watching. Cleared the code. Next fill-up same issue.

I ordered a new purge valve (L1MZ5K291M). Replaced it last week. Cleared codes. So far so good even after a fill up.
