lbz28

Hello, I can't get the computer codes for my 94 z28 (it has automatic transmission). If I use a OBD1 scanner to get codes, it turns both fans on.

Does anyone knows if when disabling the anti theft system, the computer codes could not be retrieved?

Also this car runs hot, both fans will not turn on when needed, the only way they turn on is when braking for large distances (500 m).

I've already changed all temperature sensors, thermostat, water pump, hoses...
