:D That's funny. I'm experiencing the same problem with my LS.
Your going to need to pull the code. I'm experiencing a No2 speed sensor, and O2 sensor problem. The trac is related to motion, so ABS, Motion Sensors, or Trac failure all together are your possible areas.
If it's one of your motion sensors, let me know. I'm planning on getting parts from my distributor, and I can buy yours with mine--discount, sort of.
