how much dose a tune-up for a 2001 ford traurs cost ?

I suppose it depends on how it runs,and how thorough you want to be.No set price. Replacing the spark plugs is #1 on the agenda,not a big labor or parts cost-that alone,should cure a lot of running problems. Going deeper,you can change air and fuel filters,spark plug wires,pcv valve,etc. If you want to keep the car,you wouldn't be wasting money to service the transmission,motor oil change and filter,change brake and power steering fluid and antifreeze.

Why do you think you need a tuneup? How many miles do you have on the car?
