I have a 1999 SC2 that is idling rough. It does burn a little oil too. I did a compression test. I had never done one before. For the dry test, all 4 were 195 to 210. When I did the wet test the pressure increased significantly, 270 to 300. I did not expect that much of an increase. According to what I have read, a significant increase in pressure means the piston rings are worn. I am not sure that I trust the results of the test. Could I have added too much oil?
