    Hi, this evening my check engine light came on in my 1991 780. This
    happened after a few minutes of driving and a slightly harder than
    normal stop followed by getting up to freeway speed. The car seems to
    driving normal with no starting or stalling problems (so far).

    Here are the codes the computer gave -




    I used to have a 240 that had issues after the check engine light came
    on. The problems got progressively worse and the issue was finally
    traced to a bad O2 sensor after many bad diagnoses. Is anyone
    familiar with the 700 series who have had the same problem with the
    check engine light and similar codes?

    These are the classic vacuum leak codes. Also commonly caused by fuel
