You didn't tell us from what point the arc is coming; if it is arcing from the sparkplug lead on the side to the manifold (this is at chassis ground) then either the lead has lost its ability to insulate or the plug is totally open (this latter would be rare).
If you check at night away from lights with the engine running, you may see other points of leakage too. This is unfortunately common with crappy factory leads.
If you replace them, I would recommend you buy a silicone insulated lead set for your vehicle; they are nearly impervious to heat and aging although they do have inferior resistance to abrasion to which they aren't likely to be exposed.

How do you check if you spark plug is firing


Take out the spark plug, place wire back on plug. Hold wire/plug by wire's boot, so firing end of plug is close to (1/4" away from) a ground like the engine block, exhaust manifold, etc.

Have some one turn the key so engine turns over.

If you have good spark you will have a bright blue spark from plug to exhaust manifold. you better use well insulated pliars to hold plug or a piece of wood to hold it to a ground to see if it sparks. good-day !

We r trying to change the spark plugs in a 2002 kia sedona. and we r trying to take the intake manifold off but wont come off. we have loosened every bolt. any suggestions? thanks..


According to what I can find, you don't need to take the intake manifold off:
3.5L Engine

  1. Disconnect the negative battery cable.
    WARNING When disconnecting the cable, only pull on the plug cable boot, never on the wire itself!
  2. Detach the spark plug cable from the spark plug.
  3. Use spark plug wrench to remove the spark plug(s) from the cylinder head.
    WARNING Do not let any dirt or debris get into the engine through the spark plugs holes while when are removed.

To install:
  1. Install the spark plug and tighten to 15-22 ft. lbs. (20-30 Nm). Do not over-tighten the spark plug.
  2. Attach the spark plug wire(s) to the spark plug(s).
  3. Connect the negative battery cable.

How many spark plugs are on the mercury milan 2007. I only found 3.


For 2007 Mercury Milan 3.0L SFI DOHC 6cyl the upper intake manifold must be removed to access the RH spark plugs only.
  1. Remove the upper intake manifold, if removing the RH spark plugs. Refer to the Intake Manifold procedure in the Engine Mechanical Section
  2. Disconnect the 6 ignition coil-on-plug electrical connectors.
    NOTE When removing the ignition coil-on-plugs, a slight twisting motion will break the seal and ease removal.
  3. Remove the 6 bolts and the 6 ignition coil-on-plugs.
    WARNING Only use hand tools when removing or installing the spark plugs, or damage can occur to the cylinder head or spark plug.
    NOTE Use compressed air to remove any foreign material in the spark plug well before removing the spark plugs.
  4. Remove the 6 spark plugs.

To install:
  1. Inspect the spark plugs, as outlined in this section.
  2. Inspect the 6 spark plugs.
  3. Adjust the spark plug gap, as necessary, to 1.32-1.42mm (0.052-0.056 in.).
    WARNING Only use hand tools when removing or installing the spark plugs, or damage can occur to the cylinder head or spark plug.
  4. Install the 6 spark plugs. Tighten to 15 Nm (11 lb-ft).
    NOTE Apply a small amount of dielectric grease to the inside of the ignition coil-on-plug boots before attaching to the spark plugs.
  5. Install the 6 ignition coil-on-plugs and the 6 bolts. Tighten to 7 Nm (62 lb-in).
  6. Connect the 6 ignition coil-on-plug electrical connectors.
  7. If removed, install the upper intake manifold

Hope helps.

I need to know how to change the back three spark plugs on my 2008 ford edge , do i remove the manifold.to get to them, is it safe


Yes, you will have to remove the intake manifold. If you are mechanically inclined, it's not that hard. Looks complicated because of all the wires and hoses. Just take your time, keep track of everything you do, take notes if you have to, so everything goes back together the same way it came apart. Since you are going to all this trouble be sure you buy a premium spark plug. I wouldn't use Champion or Ford products. NGK Iridium would be my choice if they are available.

Step 1: Disconnect the negative wire to the battery. I did this to be safe.

Step 2: Disconnect the oxygen sensor from the air intake. Do not pull from the wires only pull from the boot. Be careful not to break the sensor either


Step 3: Pull the tube connected to the left side of the air intake off then remove the air intake.


Step 4: Disconnect the map sensor and all other electric components that are attached to the manifold


Step 5: Disconnect the cable that is connected to the throttle body (you do not have to take the throttle body off of the manifold to do this).


Step 6: On the left hand side of the manifold there are 2 manifold support brackets loosen them up but do not take them off. When they are loose just pull the top part of the bracket that is connected to the manifold back and off the screws. .


Step 7: On the right hand side of the manifold there is another support bracket that is connected to the throttle body. First take off the screws then where the support bracket connects to the cylinder bellow the manifold loosen the two bolts until you are able to slide the bracket out of the way.


Step 8: On top of the manifold there are six bolts unscrew them.


Step 9: Important! Before you remove the manifold to get to the spark plugs be very careful and remove the manifold by lifting it straight up and then pull it towards you slow. The reason for this is because there is a valve connected to the manifold directly in the back that you do not want to break. The tubes that are connected are long enough so you can take the whole manifold and place it to the right just out of the way so you can get to the spark plugs. (before changing the spark plug it is recommended that you take compressed air and blow away the dirt surrounding the spark plug area. This is done so that no dirt gets into the combustion chamber when you remove the spark plug.)


Step 10: Once the manifold is out of the way disconnect the electric connectors that are attached to every spark plug. Pull them from the boot of the connector.


Step 11: Unbolt the spark plug tube then pull it straight out and then with the spark plug socket unscrew the spark plug and replace it with a new one (repeat 6 times).


Step 12: After the spark plugs are in on the left hand side of the engine in the back you will see a tube that says pcv. Remove the tube from the engine and unscrew the valve and replace it with a new one.


Step 13: Put everything back and you are good to go.
Once again thank you and I hope this was helpful.

Spark plug location in a 2001 ford escape


Need to remove upper intake manifold to reach valve cover close to firewall.
1) The location of spark plugs 456 are under the plastic shield in front of the engine. It takes an 8mm socket to remove the three bolts holding the shield once the shield is removed you will see a coil for each spark plug. Use the 8mm socket and remove the coil and rubber boots. You will now see the spark plug (note there are not any spark plug wires).
2) The location of spark plugs 123 are located to the rear of the eng. You have to remove the air intake manifold in order to get to the spark plus. Remove the throttle wire then remove the other items on top of the intake manifold.

I keep getting a notice that the #2 and #4 cyclinder is misfiring. I went to change the plugs, but could not locate them from the top of the engine. Where are the plugs located at?

Remove the EGR valve mounts so you can slide the manifold out. Disconnet all vacuum lines from manifold and the air filter inlet closet to manifold. Just take a general look and ensure you have all wiring and tubing disconnected then slide the manifold off the eng and EGR valve. NOW MAKE SURE you cover all intake holes (leading into the engine) with paper towels to prevent droping screws etc into the engine. Then follow step 1 above
