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 fine... 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? TIA, Chuck
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. E
