how many miles do I have to have before I get a tune up
If you have an owners manual, it will have reccomended intervals. It really depends on what type of driving you do (city or highway) I replace my plugs every 30,000 and the wire, cap rotor every 50 K. Thats just my preference, but most mechanics will agree
