alright.. so i FINALLY got my car back on the road.. drive it 10 feet, and it goes into reduced engine power mode... the car just got a 408 build and was running just fine until a crank pulley mishap. got the new crank pulley on and took it out for the drive and got the error code..


im getting a TAC module performance code (throttle actuator control)

and a TAC module fault code (throttle actuator control)



so im guessing my TAC module has gone bad... im guessing that its a dealer only part?? is there any way to fix it rather than replacing it??? anybody had this problem before with the electric throttle body on the corvettes??
