96 SW1, runs great, then terrible

  1. Hi,

    This car (65k miles) runs very well 99% of the time. But every so often, it
    starts to run horrible -- coughing, sputtering, stalls. There is a strong
    smell of sulfur from the exhaust. Then when I restart it, everything is

    I'm thinking this has got to be some computer/sensor error, because if
    something were really wrong, it would always run bad. Anyone have an
    insight into this?

    try changing the pvc valve first, so cheap & easy; turn key on & off 5 times
    without start to reset, if no go, try the oxygen sensor. I am not a mechanic,
    I just know this worked for me.

    I highly suspect the fuel pump.
