N14. Currently trying to chase down 431 code. Intermittent 432 code and idle only. New ECM have tried 2 TPS. Ran new wires directly to pins 6,9,10 on the ecm connector from the foot feed and still getting this code. Jakes also quit working after I bypassed the factory harness and will not come back if I plug factory pins in.
96 w900 431 code
