I need to change out the spark plugs for a 2004 Dodge neon. The main problem is getting the rubber boot and wire off the plug in order to access it for replacement. It seems to be attached tightly to the plugs. How can I remove it without damaging the spark plugs?
Just pull hard, it does seem pretty tough, but you won't damage anything as long as its a hard consistent pull. Don't TUG, but pull increasing the pressure until it comes out. It needs to be a snug fit in there to keep debris/moisture etc from getting to your spark plug!

The spark plug wires might be bad, Are the coil packs a wires together in one? With the engine off, loosen each plug wire so as to when you start it you can not have to battle with it First do this with dry floor, rubber sole shoos and a pare of rubber or vinyl gloves. As its running pull 1 plug wire off at a time. When you get to a plug that doesn't change the sound of the motor you've found your miss. Did the CK engine light come on?
Darien, just because it's getting good spark at the spark plug wires doesn't mean that the spark plugs are firing. Now let's get your girlfriend happy again, Remove those spark plugs, check the center electrode and see if they are worn down, if they are worn down, change all 4, Good luck, Gary
Be careful, when its running, slowly pull each spark plug wire up, if you see sparking coming out of the side of the spark plug boot, replace the wires and spark plugs. Use the correct Champion Spark Plugs.
Remove one spark plug wire / using correct size spark plug wrench with / rubber boot designed for spark plugs (deep well socket with rubber boot) remove (1) spark plug / gap new replacement spark plug to specs / install replacement spark plug by hand into head of engine /finger tight /using spark plug socket and rachet finish tighting spark plug / tighten just beyond snug being careful to not over tighten and breaking spark plug ..if in doubt about the proper tighting consult motor manual for torque specs. use torque specs in conjunction with appropiate torque wrench . Re-install removed spark plug wire ...proceed to remaining spark plugs doing one at a time until completed.
Hi! When replacing the plugs and wires on this model be sure there is no oil in spark plug wells. You will notice the oil on the plug wire boot when removing it. If there is any oil on any of the boots the valve cover gasket and spark plug tube seals will need to be replaced or the misfire code you mentioned will return. Hope this information helps!
First off, on this model you don't have plug wires, you have coil packs with a boot and coil connected to the pack. The boot slides on the tops of the spark plug. The good thing about this is that you don't have to mark each wire to its location.
So to replace the plugs you need to disconnect the electrical connector to the coil pack and then unbolt the two bolts that mount the pack down, then remove the pack.
Next with a ratchet, an extension and a special spark plug socket, which has an insulator inside to protect the porcelain from getting cracked, remove the spark plugs.
Next step is to replace the plug, usually I slide off the boot from the coil pack and then remove the coil from inside the boot and slide the boot over the spark plug and start to thread the plug back in. Using this method allows to you feel if you are threading the plug in right. Then with a torque wrench you would torque the spark plug to the specs for the type of engine you have.
Next reinstall the coil pack with the two mounting bolts, it is only necessary to hand tigthen the two bolts. Then plug back in the electrical connector and continue this process on the next 5 spark plugs.
Take your time, and follow your ignition wires from the coil pack to the engine. The ignition wires will most likely be either gray or black. You are looking for 4 thick wires that lead into a valve cover, and under square black rubber "boots" located in a row next to each other. Once yo pull up the boot, the spark plug will be directly below the boots. Check this picture to see whjat I am referencing http://www.allpar.com/images/neon-1995/engine.jpg
you will see the 4 square boot toward the top left of the picture closest to the windshield.
