tune up

The word tune-up throws a wide loop. It means different things to different people. Change the spark plugs and plug wires-- dist. cap and rotor, where applicable. Change all filters. If changing fuel filter make sure there is no pressure on the system before taking any lines loose. Use a gage and check fuel pressure. If computer controlled use a scanner that will show live engine data, see if everything looks ok? Check for trouble codes. How long since a lube job, oil and filter change. Check all fluid levels. That is the short list.
