JK troubleshooting HELP!

I have a 2008 jeep Wrangler unlimited 6 speed. The check engine light and 'esp off' light comes on. The dealer can't find the problem. Once they come on, the engine will hesitate. Turning the ESP switch doesn't have any affect. I am wondering if anyone has had this problem.

I had the check engine light and it was just the gas cap.

A good start would be to find out what CEL code it's throwing. Then maybe we can start to help Otherwise, throw darts at a diag chart Equally useful.
Check for loose connections, things that are obviously broken.
Is the rig modded?
Did you change anything right before this started?
MIGHT be TPS, going by what you're telling me, but do NOT quote me on that! Mark W.
