If you didnt do the tune up yourself, you never know what was or wasnt done for sure. Youd be surprised at how many places dont do the maintnance you ask for but still charge you for it. Also the wires wouldnt be replaced in a "tune up"... Maybe you have bad gas (gasoline) Injectors? Fuel pump on its way out? Fuel filter??
