The carb wiring is hooked into computer, then into the ignition module to retard timing when the knock sensor "hears" noise. (clacking lifters can often trigger it to retard timing and reduce power) Non-working accelerator pump in the carb, bad vacuum advance, intake or carb base vacuum leak, sticking intake valve (common on '80 motors), bad brake booster, timing too retarded and/or messed up distributor mechanical advance can all cause backfires.
