I have a 1998 Volvo V70 T5 with manual transmission; my Service light has been on for a couple of months. After two minutes it goes out. Then last week my Check Engine light came on. I had the car diagnosed only to find out I had a misfire in #3 cylinder. The Check Engine light was reset but not the Service light which is still on! What gives?  
  
 Oh, I should mention that I religiously change all my fluids and all belts ands runs famously. The odometer has under 106,000 miles on it.  
  
  
  
 Thank you , in advance, for your response. . .

Either whoever performed your last oil change did not reset the Service light, OR the car really is ready for service.

The Check Engine light means that the computer has determined that something is wrong, and there is a stored code (in this case, a cylinder misfire). Your owner’s manual should tell you why the Service Engine light comes on – is it based on mileage (and possibly time)? As mentioned above, whoever did the last service (not repair) may have neglected to reset the Service light.
