  1. what codes did you have to begin with that made you replace all these sensors?

    No power possibilities:
    1. clogged catalytic converter
    2. clogged fuel filter
    3. low fuel pressure
    4. slipping transmission
    5. clogged injectors
    6. crank case overfilled
    7. poor ignition
    8. clogged air flow system
    9. failed IAT – Intake Air Temperature Sensor
    10. ECM failure
