Default Check your injectors

Injectors that are shorted out can destroy the driver circuits of the ECM.

What is going bad?

If you leave a bad sensor on the car long enough, it will take out the ECM.

What is ac code?

You have CCM = 1.0 will be displayed on the dash
ECM = 4.0
ABS = 9.0

Which system generated the 70 and 71?

Without a xref, those codes are useless.
Put a paperclip in the top right and bottom left ALDL connector and turn the key to ON.
Read the codes and come back and tell us, also get a FSM. It will save you 10 times what you pay for it.
