Should I give my car a tune up?

A tune up is a straightforward task that just about anybody can do.  This will make your automobile more fuel-efficient.  This applies for any motorized vehicle.  The filters are a neat place to start.  Depending how frequently you do a tune up will affect how much of an improvement that you will see.  Most engineers suggest a fine-tune by 60,000 miles.

The engine air purifying device can be your first fine tune item.  The air purifier is located over a carburetor on older vehicles.  The air filter is in the airbox on fuel injected motors.  The fuel filter can be located anywhere between your engine and the fuel tank and should also be replaced.  If the fuel filter is clogged it can make your engine run lean.

Many times if your check engine light has been on it is thanks to the o2 sensor not working in the right way.  This is normally only replaced when it fails but usually won't last long anyways.  Now is also a good time to have your transmission filter replaced.  If the transmission filter has a lot of miles on it the transmission could be slipping.

Replacing this might need to be done by an engineer, unless you are feeling snug enough to it.  The filter is generally found under the transmission pan.  The transmission filter will typically pull straight down and out.  Unless you've got the infrequent, screw on filter like saturns.

The ignition system is also very important and needs attention.  The spark plug wires will usually wear out even faster than the 60,000 mile fine-tune.  Try half that mileage and it'll save you money and difficulties.  Spark plug wires wear out and lose resistance, making the auto run rough and use more fuel.  While replacing the spark plug wires it's also a good idea to replace the distributor cap and rotor.

The engine's distributor cap will come off straightforward, typically with two screws.  It could be quickest to take away the distributor cap first to keep the wires running to the correct spark plug.  When the cap is removed, the rotor will be located under it and typically has a push in tab to release it.  Reload the new distributer cap and proceed to remove one spark plug wire only.

Now it's time to replace the spark plugs.  The spark plugs will usually come out with a five / 8" or thirteen / 16" socket.  Replace the spark plug with a new compatible plug.  Check the gap with a feeler gauge and tap on or pry the electrode back in until you have got the gap the size it needs to be.  Most engines run the spark plug opening between .030" and .045" dependent on the car.

Now refer to the finish line set up on the old distributor cap.  Trace the one wire back to where it needs to be on the new cap.  Do this to all the wire and plugs so they can't be mixed up.  The ignition timing should also be checked by connecting a timing light to one spark plug wire.  The timing setting should be around 8 to 12 degrees advanced or 0 on newer automobiles.

The actual timing spec, together with the spark plug gap, will be displayed under the hood on a tag.  Also if unjustifiable oil was discovered in the air purifying device, you should replace the PCV ( positive crankcase valve ) which will be usually be found in the head, valve cover or air cleaner / box.  If there is no oil in the air filter then the PCV valve is o.k.  This will return your auto to the factory oem specs and will often improve the power, smoothness and fuel economy.
