I recently had a tune-up, the air Maf flow sensor, oil & air filter changed. Today the "Service Engine Soon" light came on for about 30 seconds. What is that trying to tell me? Service what part of the engine?

It might not be related to the work you had done. Have someone check the codes in your ECM. Your local Autozone or Advance Auto Parts might do this for free. If they do, there should be a code stored anytime the check/service engine light comes on. The code will localize the problem.
