What is a good code reader to use? I'm wanting to get one that can display the history if I can.
How can it possibly EVER pay for itself? OBD-I code readers are functionally equivalent to a paper clip.
Even OBD-II has "hard" codes and "soft" codes. Hard codes go away once the condition lifts, but soft codes do not until they are cleared or the always-on power fails.
OBD-II also has "pending" (unconfirmed) codes that can be useful for diagnosing intermittents.
None of this is a function of the reader. It's in your PCM.
