    Does your car idle erratically? does it struggle accelerating? Its a possibility of the cam lobe sensor being faulty but I havent heard of many cases.

    A lambda sensor does indeed measure oxygen content of the exhaust, adjusting the mix accordingly. But the lambda emissions reading is a measure of the stoichiometric mix and will easily identify an engine which is running rich or lean.
    Post cat lambda sensors are fitted to monitor cat efficiency but there is no post cat lambda fitted on the M50 325 engine. They were only fitted when OBDII came in.
