My '04 coupe just turned past 50K miles. Outside of regularly schedule oil and air filter changes and chassis lubes. There's never been any engine work and it's still performing well. I am noticing that the engine sometimes hesitates to fire up on the first key turn. Is it time for a tune up, and if so, what needs to be checked?
