Need help... CEL P0455... What could it be? Ideas?
Alright, so I'm trying to finish up some stuff on the truck and one of them is getting the smog situation worked out.
I've got everything hooked up and now I have this code.. P0455 Evap Emissions Control System Leak (large). I have a pretty good idea of what it can be, but I'm coming to you to see if you guys have any ideas that I haven't thought of already.
So lets hear it! What could this be?!?
