Title: Mazda 6 S 2004 3.0 v-6 -spark plug removal (rear3)
Article: Congratulations New or used Mazda owner. You have made a great choice
in buying this model.I have recently encountered a dilemma however; when
changing the spark plugs- you are going to need 1.)about 2 or 3 hrs., a 10mm.
socket on 3/8 ratchet, and a 5/16 or metric equiv in order to simply expose the
back 3. You're front three are easy as pie-simply unbolt the spark plug
(electrical device)and gently pull exposing plug.The back 3 are underneath the
intake manifold. First carefully undo the 3 bolts to remove dust cover(do not be
rough as they are costly)and then proceed to unbolt intake manifold. undo
adjoining vacuum lines. *[Note although the bolts will not come out all the way
just loosen them all the way ;they will stay in the manifold but it will come
out with them in it.]* Be extremely careful when removing manifold as it has
gaskets
that can tear. Most local parts stores don't have them -you gotta buy them at
the dealership. now replace plugs. and reverse the order to reassemble. Now
thank God that it'll be a while before you do it again!{I personally recommend
using N.G.K "iridium" spark plugs} they really make a phenomenal difference!
For a Jeep engine, it has 6.
.034
there are 3 in the front and 3 in the back if its a 6cyl.
it not uses 12 spark plugs, it uses 24 sparks plug due that was the original design from ford's engineerings
Look at this: http://autorepair.about.com/library/firing_orders/bl-fo-12987.htm
sounds like either a spark problem or even a fuel filter replace the two. Replace the spark plugs check the wires and replace the fuel filter. $20 max if you do it your self
4 cyl - easy remove plastic engine cover and they are right there. The 6cyl is much more complex the upper intake plenum has to come off.
gap your plugs at 0.35 drive safe actually the CORRECT gap for these is .45 no wonder they told you to drive safe, must have known it would be running bad!!!
Replace the crank shaft position sensor- located on the top right hand side of the bell housing. Very difficult to replace but it will do all you have described
.044 inch
all depends if it's a 6cyl. or a v8.
Should be .035"
