    Hi Bill your engine management system should be:Motronic ME7.5, is this so?
    if so your fault code is being flagged because of three possible causes
    1 induction leaks
    2 air mass meter faults
    3 throttle valve control faults
    start with good old basic mechanical checks,then move on to INPUT/OUTPUT checks at the ECU.
    Regards Mark.
