These are the OBD I codes: 24, 57, 58, 73
Symptoms: Engine occasionally cuts out while driving
I have a book that tells what the codes mean but it lists multiple possibilities for each code. I need some help narrowing this down.
Code 24

Code 57:
-(Cars ONLY): Octane adjust circuit grounded

Code 58:

Code 73:
