On the same note, I have the same emissions fault as Mike....
I checked the canister and the hoses looked fine but then I followed it back to this box:
Is it supposed to look like this (apologies for blurry - it was dark)? The white part looks like it should be inside that box and also it looks like the edges of that box are open. Does this look normal? What is this box? Could this be the source of my flow problems?
I sent the pic to Mike last night, he was going to check his.
Cheers!
