Unfortunately all you can do is twist on them and pull, most of the time they break, and you have to pull the rest of the end off with pliars, just try twisting back and forth is all i can suggest

    How To Find An Electrical Engine Miss


    One way to find an engine miss, start the vehicle, and with a pair of leather gloves, (so you don't get a jolt and you might want to remove each wire boot and reinstall with the motor not running, this will help ease removal of the spark plug wires when the motor's running, also spraying some WD-40 and twisting the spark plug wire boots will help in removal of the spark plug wire). You'll want remove 1 spark plug at a time, if the engine bogs down or idle drops, put the wire back on, go to the next spark plug wire, until you get to the spark plug wire that has no effect on the running of the motor when you remove the spark plug wire from the plug, that is the cylinder that has a problem. The problem causing this could be the spark plug (wrong spark plug gap), a bad spark plug wire, the terminal on the distributor cap, or even an internal engine problems i.e, intake or exhaust valves, bent pushrods, broken or weak valve springs, or bad compression rings on the piston. This will help you narrow it down to what cylinder it is. If removing all of them doesn't make much difference, there could be a vacuum leak, caused by a broken or disconnected vacuum hose or fuel delivery problems, plugged fuel filter, low fuel pressure, or a bad fuel pressure regulator.

    How to replace a sparkplugs for a mitsubishi montero xls 2002


      • 1 Cool the engine before attempting to remove any spark plugs.
      • 2 Remove the spark plug wires located across the top of the Eclipse model's engine. The spark plug wires connected to the spark plugs are the flat circular ends. Grab the wire around the circle and twist to unlock the wire. Lift up on the wire to remove it from the engine. Some models with ignition coils above the spark plug may require you to unhook the wire from the ignition coil to remove the wire.
      • 3 Drop the socket with the extension and socket wrench attached into the cylinder well and on top of the spark plug. Turn the socket wrench to unscrew and pull the spark plug out of the engine.
      • 4 Spray silicone spray into the cylinder well and onto the new spark plug threads.
      • 5 Insert the new spark plug into the socket with the threads sticking out. Slide the socket into the cylinder well and gently turn the wrench to the right to thread the spark plug into the cylinder head.
      • 6 Use the tension tool to test the tension or torque of the new spark plug. Set the tension to the specifications listed on the spark plug package.
      • 7 Reattach the spark plug wire to the new spark plug.
      • 8 Continue this process with the other spark plugs. Be sure to only complete one spark plug replacement at a time.

    Inspection

    Inspect for the correct routing of the spark plug wires. Improper routing may cause cross-firing. Inspect each wire for any signs of cranks or splits in the wire. Inspect each plug wire boot for tearing, piercing, arcing, carbon tracking or a corroded terminal.
    If there is any corrosion, carbon tracking or arcing indicated on a plug wire boot or terminal, both the plug wire and component it was connected to should be replaced.

    I want to replace the spark plugs and wires on my 03 impala 3.8l. There is a heat shield on th eplug. Can this shield be removed? is there a special tool to remove the wires?


    The heat shield on the plug wires are there to keep the heat off the wires.I believe they are only on the rear ones.Yes they do come off.They need to be installed on the new ones.There are some special pliers that are for removing the wires but sometimes they ruin the wires.The best way to remove the plug wires is to grab and twist back and forth and out.What happens is the rubber part kind of sticks on the porcelin part of the plug and you have to twist it to break it loose.Hope this helps.Good luck.

    Where are the spark plugs located? and how do I get to them?


    There are no spark plug wires on the 2000-up Northstar engines. They use coil on plug design. First remove the engine service cover.(The Pretty plastic peice that has the Cadillac symbol on it) Then disconnect the coil connector which sits to the right of the coil and should just snap off by hand. Next If you remove the screws that holds the coil pack (8 screws) to the top of the cam covers, you will see 4 black round rubber boots that sit on top of the plugs. Pull the boots free to expose the plugs. The tops of the spark plugs sit directly underneath
