chadz34 Posted March 8, 2006 Report Share Posted March 8, 2006 I would do a tune-up. I found that out. Tune-up's do miracles. Sounds like it could be an O2 as well. Quote Link to comment Share on other sites More sharing options...

joey b Posted March 8, 2006 Report Share Posted March 8, 2006 flashing SES light means cylinder misfire. That would also cause vibration. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted March 8, 2006 Report Share Posted March 8, 2006 Id check the coils. A bad plug although would cause vibration, it wouldnt set a SES light. Quote Link to comment Share on other sites More sharing options...
