    Mitsubishi Space Wagon GDI CO Level very high then low Archived Message

    Anyone got any ideas?
    2001 GDI Space wagon co level fine one minute then jumps up to 9% at idle. Only fault code was lambda sensor (pre cat) open circuit. Cleared code and when the emissions are ok the lambda sensor is switching fine, code has not returned. 1st & 2nd throttle position sensor readings are about the same - 1.25 volts at idle, would expect these to normally be the total of 5 volts but no info availabe.
    Any info greatly received.
    Thank You
