* What constitutes a "tune-up": The definition of a tune-up has changed over the years. Older vehicles required more extensive work (points, condenser, distributor cap and rotor). Modern vehicles like your Impala, with computer controlled ignition systems, usually only need certain components replaced or checked. A "tune-up" might encompass just replacing spark plugs and air filter, or it could involve additional items such as fuel filter, PCV valve, throttle body cleaning, etc.
* Where you get the service: Dealerships generally charge more than independent mechanics or chain auto parts stores.
* Parts quality: Using OEM (Original Equipment Manufacturer) parts will cost more than aftermarket parts.
* Labor rates: Labor rates vary widely by location and the shop's overhead.
Rough Estimates:
A basic tune-up (spark plugs and air filter) might cost anywhere from $100 to $300. A more comprehensive tune-up, including additional items like the fuel filter or a throttle body cleaning, could easily reach $300 to $500 or more.
Recommendation:
To get an accurate estimate, I strongly recommend calling several local mechanics or auto parts stores in your area and describing what you'd like included in the tune-up. Be sure to ask for a detailed breakdown of the costs (parts and labor). This will give you a good understanding of the price range for your specific situation.
