No, the CEL still comes on. I just use the Scangauge to turn it off right away. I haven't tried adjusting the idle yet. I'm not worried about damaging the stock TB, I'm just wary of opening it since it's almost brand new with less than 2,000 miles on it. If I open it up to do the chip swap, I want to know it's going to fix the problem.

You won't damage the TB if you open it, since all you're really doing is drilling off some rivets. You can always get it sealed back up to OEM specs using a rivet gun (I used screws myself). I think you should give it a shot if you can and see if that solves the problem. Won't take more than 10 mins to do the swap.

Then again, you may want to adjust the idle screw first, which is even easier to do.

I guess I'll give the chip swap a try if the problems come back. I reconnected the battery and got no CEL or oscillation on start up this morning so I'll give it a few days *fingers crossed*
