    Scratching my head on this.Its had a tendancy to stumble at idle and sometimes cutout but restart.
    It now stll starts ok from cold but sometimes wont start after it has warmed up.
    Having to use my ancient Crypton ACT to get codes as it has the black/white connectors.It always has had these codes which always return straight away.
    01247 ACF solenoid
    17923 Intake manifold air control solenoid
    17935 Cam position actuator
    16486 Air mass signal low
    16519 o2 heater circuit
    16518 o2 sensor no activity
    Oxy sensor output stays at 0.46 v with no movement.
    Car actually drives OK.
    Have tried substituting air mass and o2 with no change.
    Cant help thinking that these are all linked but I have no wiring diagram.
    Any pointers please?
    Thanks,
    Tony
