The only "Code" that my '63 ever gives me is the "COLD" light on the dash face, letting me know that "miss cantankerous" isn't moving out of the driveway without stalling until I let her carburetor warm up for 5 minutes. ;?)
This board is dedicated to rear wheel drive Impalas that were built from 1958 to around 1976 mostly; though all Impala enthusiasts are welcome here.
Most of our board members tune their cars with a screw driver and they will not have a clue what the code is. There are some younger guys on the board who stuill have to work for a living and may know what code you have; though it would be really helpfull to know what engine we are talking about and what year it is installed in.
