Your car should receive a tune-up (often referred to as a "major service") every two years or 30,000 miles, whichever comes first. During this tune-up your car will receive some new parts that will hopefully keep it out of the shop for a while. Here's what needs to be done.

Instructions

Difficulty: Moderate

Things You’ll Need:

Step1
Replace the fuel filter. If you have a fuel-injection system, regular cleaning isn't necessary unless the injectors are clogged.
Step2
Change the spark plugs (unless they're platinum, in which case you have 30,000 more miles to go). Also examine the spark plug wires and replace as needed. A new set of high-quality wires is worth the cost. They may be permanently attached to the distributor cap, so it will have to be changed as well.
Step3
Replace the distributor cap and rotor if your car has them (some newer models with distributorless ignition don't).
Step4
Change the points and condenser if you have an older car (roughly 1978 or older) that doesn't feature electronic ignition. You'll actually want your points changed, or at least adjusted, every six months or so (if they're changed, check the ignition timing as well).
Step5
Check the ignition timing and adjust as needed (rare for a car with electronic ignition--post-1980--and some cars don't allow this at all).
Step6
Adjust the valves as needed (unless your car has hydraulic valves). Be sure to replace the valve-cover gasket as well, especially if you see oil on top of your engine.
Step7
Check the belts. Replace if worn.
Step8
Check the fluids under the hood and replenish as necessary. Change the oil and oil filter if it's been 3,000 miles since the last oil change.
Step9
Replace the air filter, which should be changed between major services--every 15,000 miles--as well.
Step10
Adjust the clutch, if you have a manual transmission (although some cars now sport self-adjusting clutches).
Step11
Service the battery, adding distilled water (if required), cleaning terminals and cable ends.
Step12
Replace the PCV (positive crankcase ventilation) valve. It can make your car run rough or stall if it gets clogged, and it's cheap and easy to replace.

Tips & Warnings

  • A tune-up isn't a cure all, but when done regularly, it can prevent a host of expensive problems.

on 3/29/2007 I'm doing a tune up for my dads 97 astro chevy van, and i tell you, its a hassle. Ofcourse, i'm new in the whole automotive scene since i'm a teen and i'm doing this for auto class in school... but before you start doing a tune up on your own, seek some advice and see if your car will be a pain in the ass to do and instead of saving your self money by doing it on your own and spending a whole day to do it, consider perhaps saving your time instead and part with the money. however, this is a great learning experience for me, so i find that its worth it.

on 6/30/2006 Do your research before purchasing a K&N air filter. I have had three ASE & GM certified mechanics tell me that they can cause a lot of problems. The oil used to coat the filter can drip/coat the mass air flow sensor in some vehicles (like my 1996 Trans AM WS6), causing the computer to do all sorts of funky things trying to compensate for the incorrect readings coming from the soiled sensor. Now, because of this thing, I need a full tune-up and my catalytic converters have been cooked, needing replacement. Some vehicles may be safer than others, but do your homework and talk to someone knowledgeable.

on 3/15/2006 When getting a tune up it is a smart thing to buy the parts you need ahead of time on your own, then pay someone to have them install the parts for you. That will save you money and you get what you want. Some tips for getting better mileage is to remove any excess weight from inside the car you can. Only leave the things you need in the car. A good investment would be a high quailty air filter (K&N, etc.) Correct tire pressure, quality spark plugs and wires, using the a/c only when you need it, using cruise control, accelerating more gradually, and using the brake less and allowing your car to slow down by rolling (be careful though). A fuel system cleaner every now and then is good as well. Another thing to consider is the kind of tires you buy, if you spend all your time on the highway, do you really need the all-terrains? Or could you use a good street tire or allseason radial. The difference could mean 1-4 miles per gallon. But hey if you want them because they look cool, that's fine, but don't be surprised to see a slight dip in mpg.
