Electrical ghost?

[Smarty39]

I've already posted this on AZ and AW...but maybe someone local can give me some insight....here is the post

So I had, what I think to be, an electrical ghost in the S last night. I was running a couple errands when all of a sudden my CEL comes on...awesome. I take it home and scan it, and a WHACK of codes comes up:

---------

Now, none of these have ever come up before so I was a little worried to say the least. I cleared the codes and went for a fairly long drive to see if they would come back. No CEL came up, but I thought I'd scan it again anyway...and NONE of the codes appeared, and still nothing this morning.

So my question is....what the HELL could it have been? Anyone experience this before? Sorry for the long-winded post

Re: Electrical ghost?

Since they all seem to be ground related my first guess would be to check all ground for corrosion or loose connections.
