suddenly, it starts running really rough...

Everything on the Volvo S80. Sometimes called an "executive car", the S80 was Volvo's top-of-the-line passenger car. P2 platform.

Post by bajaman123 »

1999 S80 T6. Car was running great and then suddenly acted like it dropped a cylinder. Very rough running, check engine light on with "Emissions Service Required" displayed.

I suspect a bad coil (it eats these like candy) or a spark plug....any other ideas before I have it towed?

Thanks!

might be O2 (lambda) Oxygen Sensor failed, on my S60 it has 2, a front and rear, front was bad.
Symptom was revs suddenly went down or up, most of the time revs were higher then normal & it's related to Emission test fail
