64 , 139 , 97 , 198 , 176 , 02.
DTC 64 - Bank 2 (Right Front) Heated Oxygen Sensor (HO2S) #1 Circuit (Lean Exhaust Indicated)
DTC 97 - VSS Output Circuit

The other codes 139,176,198 do not exist. Make sure you have the right codes.1994-1996 Corvette ECM, CCM and ASR/EBTCM codes are accessed placing the jumper wire in ALDL connector positions 4 and 12. GM used numerals in place of alphas on all 1994 and up Corvettes at the ALDL. The ALDL numerals start with 1 in the upper left hand position and 9 in the lower left position. Install one end of the the jumper wire 4 positions from the upper right. Place the other end of your jumper wire in the position directly below number 4.
