Need some help here I have a 2007 Z06 which keeps going into reduced power seemingly at random times. It has had the throttle body replaced twice, once years ago by a dealer and most recently by me. It has a new battery and I keep it on a trickle charger at all times, car is stock.

Most recently I stepped on the gas moderately and the tires spun a bit, which forced it into reduced power mode. I have not been able to find a common thread amongst all its episodes. I end up limping it to a parking lot shutting it down, locking it and starting it back up no problem. The check engine light will remain on for about 2-7 subsequent starts.

I had the codes read at a auto zone and got a P0606 and a P2101.

I am thinking about replacing the computer next.

Any help would be greatly appreciated.
