First, make sure the spark plug is in tight and not cross threaded (take it and put back in). If the plug is loose, pressure comes out of the cylinder and pushed the wire off.

Second, push the spark plug boot on and massage the air out of the boot.

Hope this helps.

I have replaced my gasket seals and air filter oil filter as well as my spark plugs and leads and PVC valve And now the the spark leads keep popping off how do we stop that from happening?


Are you referring to the spark plug boots that go over the spark plug top? If so, you need to push these onto the spark plug until you feel a click...which means they should be properly connected...same feel on the other end of the spark plug wires...you should feel a click as they connect to the spark box individually. Hope this helps.

Why do my spark plug wires I'm my 1994 ford


Probably not seated well on the plug. When you push the plug wire boot over the plug, you have to make sure the wire end terminal's ring end snaps onto the spark plug. It is not connected tight until you hear the wire's end terminal snap or click onto the tip of the spark plug. If you can't hear the snap, the end of the wire may not be seating onto the spark plug tip. Push the boot back away from the spark plug wire end to investigate-the boots can get very stubborn with age-keep twisting it and pushing it till you get it moving back from end of wire. Examine the metal end tip of wire-trey to snap a spark plug down onto it now-if there is a problem with the end terminals you will see it-it may be too big to snap over the spark plug tip and hold securely, or if the ends are bent, use pliers to straighten them out. If these are aftermarket spark plug wires, the end terminals may be too small to go over the spark plug tip. You would then need a new set of spark plug wires.

I suspect you just have not pushed the wires down far enough to seat them on the plugs-push the wires onto the plugs until you hear them snap or click. Then they are seated firmly, and should not be popping off.

    My car was hooked to a machine and it said the number 2 cylinder is misfiring. What do I need to check out?


    First thing is the #2 spark plug. Pull it and see how it looks. Is it burned up? is it black and oily? Is it wet and smells like gas?

    If it is wet and/or smells like gas (most likely problem), either the spark plug wire or the coil pack is bad. I am not familiar with the 300M so you need to see which you have- either a spark plug wire going to a distributor cap or a coil pack that plugs directly into the spark plug.

    If you have a coil pack you can swap it with another cylinder and see if the problem also moves, which will prove that it is bad. If your Chrysler uses spark plug wires going to a distributor, I recommend changing the entire set because if one failed, others may follow suit. Make sure that you install each one at a time so they connect exactly how they came out and you do not compromise the firing order (just in case, check the underside of your hood for the emissions sticker, which will have the firing order information).

    If you pull the plug and it looks burned up, or black and sooty, you have another problem that will require further looking into. Keep us informed on FixYa and we are always glad to help!

    How to change plugs on 02 kia sportage


  • 1

    Keep a regular schedule for inspecting the spark plugs on your 2002 Kia Sportage. According to the official 2002 Kia Sportage owner's manual, spark plugs and ignition wires should be inspected every two years or 48,000 miles, whichever comes first.

  • 2

    Let your 2002 Kia Sportage sit for a few hours before opening the engine compartment. You want to make sure that the engine is cool before you begin working on it.

  • 3

    Pop open the hood of your Sportage and locate the ignition wires, which will be attached to the top of your engine. The 2002 Kia Sportage has a four-cylinder engine, meaning there are four spark plugs each attached to an ignition wire. The ignition wires run from the engine to the fuse box, which is located in the left side of the engine compartment.

  • 4

    Inspect the ignition wires of your 2002 Kia Sportage. These wires will need to be replaced if they appear worn.

  • 5

    Disconnect the ignition wire to your spark plugs. Grab the rubber boot located near the base of the wire and pull upward instead of yanking on the wire. Remove only one wire at a time, or mark the wires with a colored Sharpie marker before disconnecting all of them. Improperly reconnecting the ignition wires can seriously affect the performance of your Kia Sportage.

  • 6

    Attach the spark plug socket to your socket wrench. Use the socket wrench to remove the spark plug from the top of the engine's cylinder.

  • 7

    Inspect the spark plug. There will be some soot, but if the spark plug is completely covered in soot, it needs to be replaced.

  • 8

    Position your replacement spark plug in place and secure it with the spark plug socket on your socket wrench. Be careful not to overtighten the spark plug after it has been snuggly fitted.

  • 9

    Position the rubber boot of the proper ignition wire in place above the spark plug and insert it with your hands. Close the hood of your 2002 Kia Sportage

    I am not very handy but am considering changing the spark plugs in my 2001 Avalon. How is that done? Am I being foolish to try?


    no, you're not being foolish. in this economy many "first time mechanics" are forced to do what they normally would pay someone else to do. it's not a difficult job but there are some things you will need to know. first, you will need a 3/8 drive ratchet and a spark plug socket. spark plug sockets are equipped with a special rubber insert to keep the plug from breaking during removal and installation. there are two main sizes of socket, 5/8 and 13/16. when you purchase your new plugs, the store clerk will be able to tell you the proper size of socket to use. while you're at the store, they sell small packets of anti-seize lubricant. you will want to put a small amount of this lubricant on the threads of the new plugs to keep them from seizing up. when removing the plug wires from the plugs, grip them by the boot and not by the actual wire, as this could damage the wire. simply grip the boot and pull in a slight "wiggling" motion and they should pop off. make sure you keep the wires in order. ( i recommened doing one plug at a time to keep them in order) after removal of old plugs, hand tighten new plugs, then tighten with ratchet. DO NOT overtighten! snug is good enough. put a small dab of petroleum jelly on your pinky finger and lubricate the opening of the spark plug wire boot. this will help ensure a secure fit at the end of the plug. you will know when the wire is on tight because you will feel or hear a "click" or "pop". that's all there is to it. good luck!

    Okay the car has new gasket and new wires and the spark plugs wires pops out of the valve cover why is that


    If you bought after-market spark plug wires, that is not from a dealer, than sometimes the spark plug boot may be a tad short or loose on the spark plug and will slip or pop off. Take them back to the supplier in exchange for a better brand.

    What is the best way to change the spark plugs?


    The coils will need to be removed first, then take compressed air and blow out the spark plug tubes, then you can replace the spark plugs. Use only Motorcraft Platinum Spark Plugs. Unless you know what you are doing, I would recommend a repair shop.

    How do remove the spark plug wire harrness on the front of a 1990 buick century


    Use a suitable spark plug wire tool to remove wire from spark plug being careful not to end up leaving the terminal from the wire on the plug. If the terminal is ripped away from the wire you will have to repair it by spreading open the crimps and reattach to wire and recrimp. Silicone spray works well to slide the wire further past the spark plug wire boot to make the repair.Always use die-electric or silicone grease on the inside of plugs wire boot before you attach to plug, it helps removal for next time and it seals the boot so spark dont leak from boot and makes a moisture barrier as well. Now to answer your question if the wires are in a loom holder you have to take the top part of the loom holder apart to get wires out of it . The loom holder usually just pops into slots on the bottom part of the loom holder. It shouldn't be too hard to figure out
