Thanks for the info!

So I presume that I need a new charcoal canister? I'll do some research on that.

Okay, I'll make a project of cleaning the vacuum lines. (i have alldata)

I had the cat's welded some number of years ago, and there was a rattle-like sound for awhile.. but it has pretty much "dissipated" on it's own? I have a feeling that might be the issue there... Probably need to be replaced...
