Just curious what you guys think about this. For the past few weeks I've been repeatedly receiving code P0456 which from my understanding is an EVAP system leak. The thing is the code is recurring. The computer sets the code for a couple days and then it disappears for a couple days. Is this normal for a code like this and what should I be looking at first?

Check the O-ring seal on your gas cap. this cured mine for now. Also, do not fill up the tank while the engine is running.

You know why it's called God's country? Because most sane people want nothing to do with it other than seeing the pretty pictures nut jobs like us take out here.
