Re: Engine tune up???
Changing the fluids, filters, wires, plugs(make sure their gapped properly), are pretty much all the mechanics will overcharge you for and call it a tune up.
You could probably do this for under $100 yourself depending on what fluids and filters you use and if you change ALL the fluids or just the major ones.
