2006 Impala 3LT - P0455 Large Evap Leak - FIXED!! see below
I have the P0455 Large Evap Leak code after I had been prompted to tighten my gas cap. I tried to tighten the cap... it would click 3x and then I could still pull it straight out.
So I thought "Ahhh ha!, I can fix this". Bought a new cap and it clicked on real tight and would not pull straight out. So I cleared the code and after 1 day, the tighten gas cap came on again. Then eventually the P0455 popped up again.
So almost every forum I've read says to bite the bullet and take it into a shop and have it 'smoked'. But I dont have the $95 for the shop to just "look" at it. So I was hoping to get some suggestions from any of you. So, I'm always opting to learn more from the field since that's where most of the action happens anyway.
Does anyone know where the charcoal canister is located? I found what I believe is the purge or vent valve behind the gas cap door (looking from underneath the left rear quarter panel). But if anyone else has had this similar problem with any tips to help me out, I'd greatly appreciate it. Many thanks!
