Bad TB, Bad TAC module, or something else?
I have been sorting out some issues on one of my Z06s (the modified one). I sorted those out (bad cam sensor, cracked vacuum line to A/C, leaking MAP sensor on FAST intake, column lock issue, etc...). After fixing all the issues I went to take the car out for a drive and it was throwing a ton of trouble codes. I attributed those to the car being off the battery tender and the battery running dead. I cleared the codes, and the car seemed to drive fine. I took the car out again and went on a short drive (about 10 miles each way). On the way back it went into reduced power mode with a TPS sensor issue and threw TCS Errors. I was almost home and limped it home. I recorded the codes, cleared them and took it for a drive a few days later to see if they came back. Car runs and drives fine. Park it at the house and then come out later to put it in the garage. it then throws a page full of errors on start. Here is what I have recorded so far:

It has a brand new AGM battery that I installed less than six months ago as the old Optima was almost 10 years old.The car is hooked up to a tender when it is not being driven. The cables don’t show any obvious signs of corrosion. The car has 14,000 miles on it and is garaged.
