Need help identifying codes
the car is running terrible.I just replaced the radiator and the fuel pump.
Module 1 gives C12
Module 4 gives H64
Can anyone help me identify these 2 codes?

I was also able to locate some at the following: http://www.tonkabaygroup.com/vette/c4codes.html#64
Looks like the same list from a different source.
From what I can tell the C12 just means that the battery was disconnected within the last 50 key starts... sound good to ya'll?
Looking into the Oxygen sensor and circuit next....
:iagree:
