you can buy them at napa auto parts / auto zone / advanced auto / pep boys / and any auto parts store near you. don't buy the cheep plugs they only make more problems in the long run
mid grade plugs are fine
Find the spark plug wires and follow them. The coil/distributor is at one end and the spark plug is at the other. Spark plugs are a normal maintenance item - they are generally relatively easy to get to. If it is your intention to replace them, you will need a special spark plug wrench of the correct size, an extension, a handle and a feeler gage as well as the gap information for the plug and your engine. You can get these tools and information from your local auto parts store. I am sure the knowledgeable guy or gal at the counter can point out the location of the plugs as well. Do one at a time so you don't confuse the wires.
check for spark at the sparkplugs, and listen to hear the fuel pump going when key is turned on. if no pump noise and no spark it can be the auto shutdown relay located on the drivers side fender behind battery. the auto shut down shuts off power to the ignition and fuel pump if the timing belt snaps. ,,,, if you have spark and fuel pump works then check firing order on plug wires , if they are in right place then check timing , if timing belt was replaced without lining up the timing marks it wont run
Number 3 is the 3rd plug back on the passenger side. Coils are notorious for going bad, I would recommend replacing the spark plugs, while you are there. Use Auto Lite, or Motorcraft Platinum Spark plugs only.
Hello. Since you did not indicate the total miles on the vehicle I can not speak to the coils. Just replace the spark plugs. There are eight of them and then are located at the end of each of the spark plug wires on the topside of the engine under the hood. Joe
There are 6 coils that fire the spark plugs. You only need to replace the coils that are misfiring. Some autoparts stores will let you use a diagnostic meter for free. The code will tell you which cylinder is misfiring and the autoparts store can tell you the firing order so you can locate which cylinder & coil.
Unless your car is due for a tune up I would just replace the faulty coil and not the spark plugs. Dealer will always recommend replacing all the coils. Eventually another coil may fail but who knows when that will be. When you notice the symptom again just tackle it as you did this one.
can't clean spark plugs...and DO NOT buy Champion brand, use Autolite or Delco. Your plugs are accessible through the inner fenderwells...remove front wheels to get to them. P.S. do yourself a favor and do this as well, or in advance of the plugs...go to Advance Auto and buy "SeaFoam" gas additive and follow directions...drive at least 100 miles. Good Luck
unless you have a specific issue with the plugs , don't waste your money changing them
the v6 engine has the rear plugs as platinum plugs because it is near impossible to change them and modern engines
( manufacturer design fault in the location of the engine and so they fitted special plugs before installing the engine )
plugs last the life of the engine
if you are doing a "tune up" that is a waste of money as the ECM tunes the engine 60 times a minute
all you have to do for a "tune up" is to have the fault codes read for sensor problems
the spark plugs wires are directly located on top of the engine and the spark plugs are down inside the holes in the valve cover itself. I believe there are also 2 coils on top of the engine, which hide two of the spark plug wires which are attached directly to the underside of each coil, remove the coil pull it upward carefully and you will find the spark plugs for those two in the hole underneath the coil for each one. If you decide to replace the plugs, make sure to check the spark plug gap even if they tell you they are pre-gapped as pre-gapped spark plugs are usually gapped for more than one particular car and it may be incorrectly gapped for your specific vehicle. If you decide to also replace the spark plug wires, you will have to purchase the spark plug wires for the underside of each coil seperately because most local auto parts stores only sell 2 spark plug wires in the set that go onto the non-coil attached wires and plugs, and you have to purchase the coil spark plug wires seperately. So all in all you should have 4 spark plug wires, 2 that attach directly underneath the 2 coils, then 2 regular type wires that run to the other spark plugs. If you look at the valve cover and see the wires, you will see what i am saying better. Just don't forget to ask the autoparts store the spark plug gap recommended for you car, and adjust the gap on the plugs as needed. good luck.
