Customer: Hi. I'm getting a PO446 code on my 2008 Escalade and I can't seem to figure out why. I've replaced everything buy the canister and the code still persists.
JA: Thanks. Can you give me any more details about your issue?
Customer: The one interesting piece is that when I remove the gas cap while the engine
is running, the rpms drop way down but then it does recover. If I start putting fuel into the tank, the rpms react but it does recover. If I turn the vehicle off and fill the tank, when I try to start, it turns over for a few times before quitting. After that, it starts just fine and continues to do so until I open the gas cap. It seems the pressure is relieved and it has to re-pressureize.
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to Cadillac Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?
Customer: ok. Is this a robot or are you really typing to me?
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
