1998 Ford Mustang tune up

Answer 1

Tune Up Overview for 1998 Mustang

The tune up process for 1996 to 2004 Mustangs (both V6 and V8) consists of air filter cleaning or replacing; spark plug and ignition wire replacement; and a fuel filter change. In general, a tune up ensures that your car is getting air, fueland spark.

The air filter is accessible within the engine bay on the passenger side (see link titled "How to Replace Cold Air Intake on Mustangs" for more information on removing an air filter). Shaking out the loose dirt and gently brushing it may be adequate although replacement filters are usually under $15.

Spark plugs and ignition wires are located towards the top of each side of the engine on 4.6L cars and down on the sides of the engine (by the exhaust manifolds) on the 3.8/3.9L engines. You will need a special socket and universal joints to remove them.

All 1998 Mustangs will have ignition wires coming from one or more coil packs to each plug--remove and replace one at a time to avoid confusion.

The fuel filter is located just forward of the fuel tank and may have a special fitting that requires an A/C disconnect tool. In either case, fuel system should be depressurized by unplugging the emergency fuel shutoff switch (behind driver side trunk panel) and letting the car run until it runs out of gas. Then raise the rear of the car and remove clips and clamps to replace fuel filter. Make sure the arrow on the new fuel filter is in the same direction as the original one.
