The other day the vehicle started and ran rough. Turned off and restarted, ran ok and has been running that way since. Pulled codes and found P0303 was stored (Intermittent Firing on Cylinder 3.0 Any ideas what may be going on? Had the vehicle recently serviced under the Dex-Cool campaign. Any suggestion what to look for? Vehicle has 54,000 miles. Thanks.
