The TV and throttle adjustment procedure is unique to 92 & 93 Corvettes, they are the only years that have a TV cable and ASR, the adjustment is made at the ASR servo. I can e-mail you the pages from the FSM if you want to attempt it yourself, you will need an inch pound torque wrench and a 1/8" drill bit, PM me if interested.
If you choose to return to the dealer make sure they are aware of the special procedure, these cars are old and they may not have a tech who understands that. If they adjusted it correctly the cable may be bad and will not hold the adjustment.
If you drive back to the dealer drive gently, you can damage the transmission when the TV cable is not adjusted properly.
