S80 1999 Emission System Warning/Service

I noticed the car was running rough leaving this morning & the information center notice came on after a coulpe of blocks. It ran like the muffler was coming off. After stopping & an inspection, nothing was evident from that point of view. Car has 151 K & has not had a major tune-up since 80 K. Any ideas other than a major t/u?

You need to get the OBD II codes read.

First try changing the spark plugs. If that doesn't work, it's probably a bad coil pack.
