What all goes into a 4 cyl tune-up?

Question

I think plugs, plug wires, fuel filter, oil change, air filter... Anythin else? Anything that I have listed that is not necessary?

Answer 1

What you have listed depends on the condition of those parts. Oil change is needed every 3 to 4000 miles, air filters depend on the area you are in. If it is generally dusty, then between tune ups might be needed. An air filter at tune up is not a bad idea. Fuel filter is not generally done at a tune up. New plugs, new wires if they are over 50000 miles old, as well as a new distributor cap and rotor. One of the biggest things that you have not mentioned is timing the engine. At a tune up, checking the engine timing is a must.

Answer 2

Plugs are a definite, the wires may not need to be replaced, Fuel Air and oil filter for sure as wheel as Oil.
Top up all fluids and have the ball joints greased.

Answer 3

On many newer engines that have very long intervals between "tune ups", you may need to replace the timing belt and/or adjust the valves. This may be called a major tune-up. If you have an owners manual, check it for the required services for your mileage, or check the manufacturer's website for recommended service for your mileage.

Answer 4

no,everything you said are necessary.also get some throttle body cleaner and clean out the throttle body.what about the pcv valve and grease job.also check the battery terminals to see if they are clean and tight.check all fluids,like anti-freeze,brake fluid,power steering fluid.belts and hoses.if your going to do a tune-up,you might as well do it all.good luck.thats all i can think of.

Answer 5

distributor cap oil change and air filter are not always included
