I had a shop look at the codes and they said it was my O2s, so I replaced all 4. Now its back on.I ran the codes with my SCT Live wire and I belive it was code P1004? I forget the code, but I googled it and it is the Exhaust Gas Valve Canister? Some of the sites said it was a carbon (coal) filled canister and that it has a valve that is going out, the canister is cracked, or the lines are cracked.I would run the codes again, but the MIL went off.Any ideas what I'm talking about and where to find it?Also #2,When my car idles, and I turn on the defrost the idle goes crazy (it idles at 800 or so RPMs normally but it goes between 700 and 1100 with the defrost on.)  I'm thinking its electrical, and with winter coming up, I would like to fix it ASAP. Any ideas to even begin the search? I'm doing a battery relocation soon, and I was curious if you think this may fix the problem. My battery cables are in pretty bad shape.Thanks all...<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />  :TY:</blockquote>
