At some point after I reflash the ECU -- could be 10 minutes, could be 2-3 months -- these happen:
* Car won't hold an idle RPM -- goes between 500-1000
* Throttle response is crazy in 1st -- sometimes it's non-responsive, sometimes RPM drops as I add throttle. I need to rev the car to about 2k RPM to start moving
* At some point after that, the CEL and Traction lights come on
Reflashing temporarily solves the problem (with either tune). As does pulling the battery for 10 minutes.
My usual mechanic spent a month with the car as was stumped.
ANY suggestions? Thanks.

Throttle position sensor?? What code are you getting?
