To be more exact I think they said it was shorting out. It would be nice if they would actually test it instead of wiggling it and seeing if something changes.

I am still under warranty till mid next year and 85k miles, extended warranty. That's the only reason I bring it to the dealer, otherwise I do all my own work. But since I had the same codes and symptoms as 4 months ago just with a bank 1 instead of bank 2 and the cat being replaced fix that, I figured I would bring it in and they would replace the other cat under warranty and fix it again. But this guy seams to think that the bad cat is only the affect and that something on the engine is causing it to fail, shoring engine wire harness and intake manifold gasket.

This already is another dealer, my local one refuses to provide me service after I gave them such a hard time about there bad work last time, so this time I had to go out of town.

So the bad intake manifold gasket it likely correct but that's something not to hard that I would do myself. So any one have a better guess as to what else is wrong?
