My car house been down for two years now. The battery stayed unhooked the entire time it was down. No i have it back running and put a 370 with heads and a cam in it. Now since i fired it up My TCS light has been on and i cant turn in on or off. Could it take time for my CPU to reset and learn certain things again??

 

The computer doesn't need to be reset, nor does it "forget" things. The TCS light is probably warranted and due to some other issue that needs to be fixed. Go after the source of the problem, not trying to hide it by doing something to the computer.
