That said, "tune-up" in the context of a 1999 vehicle is a bit outdated. These cars typically don't require the same extensive tune-ups as older carbureted engines. Instead, focus on these maintenance items which are more relevant to a modern fuel-injected engine like the one in the Town Car:
* Spark Plugs: These are the closest to the traditional "tune-up" and should be replaced according to the manufacturer's recommendation (check your owner's manual). Often it's around 30,000-100,000 miles, depending on the type of plug and driving conditions.
* Wires (Ignition Coils): These are less frequent than spark plugs. They might last 60,000-100,000 miles or even longer, but look for signs of cracking or wear.
* Air Filter: This should be replaced every 12,000-15,000 miles, or more frequently if you drive in dusty conditions.
* Fuel Filter: This generally needs replacing every 30,000-60,000 miles.
* PCV Valve: Check and replace as needed. This is often overlooked but essential for proper engine operation.
Instead of thinking "tune-up," focus on regular maintenance based on mileage and the condition of these components. Always consult your owner's manual for the most accurate intervals specific to your vehicle's engine. If you're unsure, a mechanic can inspect your engine and advise on what needs to be done.
