I take it you have the I6 engine? Use AC Delco 41-103's for the spark plugs, these engines love these plugs. Other brands MAY cause the engine not to idle nice and smooth. Clean your throttle body with throttle body cleaner, with the battery disconnected, needs to be nice and shiny. Change the 02 sensor upstream right next to the exhaust manifold, that's the easy one to change. Also, replace the fuel filter and air filter. And of course, change your oil, Mobil 1 synthetic is the best for these. Check all your fluids also, like differential, tranny, xfer case and so on. If you do change the fluid in your tranny, use GM's new Dextron 6, will shift better and make your transmission last longer.

Show a step by step guide for a tune-up


A tune up consists of replacing the spark plugs and maybe the spark plug wires. Change the air filter too. No need to do timing. It is controlled by the cars computer. Spark plugs should last for about 100,000 miles. Air filters vary on how long they last. Check the air filter at 25,000 miles. Replace it no longer than 50,000 miles. Your car should not need a tune up for a couple more years or so.

What parts do I change to tune up my 2008 dodge caliber


For a standard tune-up, the parts needed include an air filter, oil filter, fuel filter, spark plugs, and spark plug wires. You should also have oil, transmission fluid, coolant, windshield washer fluid, and brake fluid available. A tune-up consists of topping off or replacing fluids, changing spark plugs and spark plug wires, changing the fuel, oil, and air filters, and checking the pressures of the tires. More detailed tune-ups run a diagnostic test on the vehicle to check for any codes that indicate additional issues.

Does the car have spark plug wires? i went to purchase some wires but the clerk said my car takes coil packs.. so do that mean i dont need wires for the spark plug tune-up??


So you want to tune it up , but someone has to tell you it has no wires? Have you looked at the engine at all? why do you want to do a tune up? The coils are very problem prone, and you need to use care in replacing the spark plugs, use only Auto-lite or Motorcraft platinum spark plugs, and use a silicone grease in the boots. After you remove the coil, blow compressed air down the tube an dblow out any dirt, before removing the spark plug. Wires are/were never an item for a tune up, unless they were bad. Replace the fuel filter.

HEY THERE. THE THREE SPARK PLUGS IN THE FRONT ARE EASY TO GET TO. THE THREE UP AGAINST THE FIRE WALL ARE ALMOST IMPOSSIBLE. DO I HAVE TO REMOVE THE ALTERNATOR OR ANYTHING ELSE ??? brb366@yahoo.com


Better yet I have had to lift the engine to get to those plugs.

RECOMENDATION:
Get the best spark plugs you can get so it Never needs to be done again and go to a tune up shop and have them put it in for you.

INFO: If you brake off one of those plugs you will be out the cost for a tow truck also.


Hope this tip helps.

How to preform a tune-up on my 2009 Saturn Vue


It has a maintenance recomendation from the manufacturer for replacement of the spark-plugs at 100,000 miles. You don't list mileage or V6 or L4 cylinder. Make sure engine is cold because the cylinder heads are aluminum and can be damaged if plugs are removed hot or overtightened upon reassembly. Remove spark-plug wires and replace spark-plugs. Sometimes the wires break when you remove them and will require replacement. If you coat the inside of the wires where they connect with the plugs with dielectric grease it will help prevent the wires from breaking upon future disassembly.
