My last work on one of these was an older model with the V-6 engine so my answer may or may not apply to your model/engine.

In that particular case, I found that the rear most plugs were easier to reach from inside with the engine cover out of the way. The forward plugs on each side were accessed from under the hood. Multiple extensions and swivels were needed to reach around everything to remove and install the plugs. Getting the plug boots off was the toughest part of the job. Good luck and let me know if this helps you out or not.

My sparkplug always wet with oil


Outside would be bad valve cover gaskets. Inside would be bad rings. Rings are an engine rebuild.

I cant find the spark plugs on my 1991 kia sportage


If your sportage has the 4 cylinder engine, there is a plastic cover over the engine that is held down by 4 bolts, one at each corner. Remove the bolts with a 10mm socket and lift he cover off and lay it aside. You will see the spark plug wires and the 4 holes where the spark plugs are. The spark plugs are about 4 inches down into the holes. Be careful removing the spark plug wires, they will be tight, and you will have to rotate them back and forth while pulling up to get them loose.

I have a 94 Pontiac Grand Am SE 5 speed standard with the 2.3L SOHC Quad 4-138 4 cyl engine. It idles fine; but when you go and shift the car bucks and has little power. Better be going 30 mph before...


This sounds like it may be misfiring, the quad four engine is famous for misfiring theres a coil cover under the top plate where the sparkplugs go, if you remove the 4 bolts and pull it up you will see the sparkplugs and that cover will contain coils and coil cover and boots, i would replace the sparkplugs and the coil cover and sparkplug boots, heres some pictures of the parts, this is where i would start it a tune up, and also check air filter and replace fuel filter,johnjohn2_31.jpgjohnjohn2_32.jpg

I can't find the location of the spark plugs on my 1997 Isuzu Rodeo LS with a V6 3.2L engine


They are underneath the coil that each cylinder has-you'll see 6 "coils"-three to side-on top of each valve cover. Remove the wire connector from the coil-remove two screws holding each coil to valve cover-carefully pull coil up away from valve cover. If it is stuck-slightly rotate coil back and forth to break it's hold on the spark plug. Use sparkplug socket and long extension to reach sparkplug down inside of valve cover. Driver's side of engine you will find one sparkplug difficult to get because of interference from brake system components. Use TWO short extensions coupled together to reach plug-when it becomes unscrewed from cyl head-lift it up-pull off one extension to clear obstruction-then pull the plug out from valve cover. (I bet you'll see some oil inside the hole where sparkplug was-(sparkplug may be wet with oil-there are seals that keep oil from leaking out of vavle cover). I DID NOT bother to replace the seals-my Rodeo is running just fine with 317,000 miles on her.

How do you change the rear sparkplugs on an 2004 Oldsmobile Alero V6 ?


On the 2002 olds alero 2.2 4 cylinder ecotec the spark plugs are located on top of the intake, under the cover that gives the engine size,it I think that yours are also located under this cover. All you have to do is remove the four bolts on top of the cover and your plugs will be under there.

Cant find sparkplugs


The spark plugs are under the aluminum engine cover plate on the top of the engine. ( The one that has the raised ribs and has the 2.4 on it) You need to remove the 4 bolts that hold the plate on the engine and then you will see the spark plugs in the center of the head in between the cam towers. Once you get the plate off, you can't miss them.

Change spark plugs on hyundai coupe v6 2.7 2002


To change the sparkplugs you have to actually remove the black and silver shield, then take the headers off. There are bolts hidden under the middle silver pieces, they pop right out. There is also a bolt under the Hyundai H logo on the cover.
