New member quesiton... Code 12?

says no signal to the pcm, yet the car runs and drive fine other than being a little rich. It's a 92 RS with 305TBI

Any thoughts on what causes it/what to fix?

It is normal. Just means that the engine isn't running at the time you are pulling codes (paper clip method?).

Code 12 is just telling you the aldl (diagnostic port) is communicating with the ECM.
