These instructions are for the 2.3 Liter 4 cylinder turbo engine, not the V-6. First of all, Set aside some time Make sure you have the best spark plugs Suggestion: Change your spark plug wires at the same time. Instructions on how to do this are not provided Tools you'll need: Socket wrench Extension for your socket wrench Spark plug socket Step 1. Unhook the spark plug wires from the spark plugs. Make sure you recall which wire you are taking off and where it goes so you'll be able to reattach it. If you have to mark each wire with numbered tape. Step 2. Loosen your 4 spark plugs using your socket wrench, socket wrench extension and spark plug socket. When loosening be gentle and don't make any sudden rapid movements. Unscrew until you are able to pull the socket wrench slowly out of the spark plug hole with the spark plug attached. Repeat step until each spark plug is removed. Step 3. Place a spark plug in the in the spark socket with the pointy end facing into the engine. Then slowly screw in a spark plug into a spark plug hole. Keeping on screwing until you begin to feel resistence. Once you do make about 3 to 4 more turns if you can, but DO NOT over tighten. Make sure the spark plugs are not extremely tight. *As a guage for tightness just recall how tight the spark plugs were before you loosened them.* Continue this step until each spark plug is inserted in its engine port/hole. Step 4. Reattach the spark plug wires to each spark plug just as they were attached before you loosened them Procedure is complete.
check that your sparkplugs are not cracked and that your wires are fully on your plugs
Does that "tapping sound" occur steadily as you apply the accelerator? It sounds like (no pun intended) there's an arc problem. Probably one of the spark plug wires was brittle when you changed the plugs and it is now broken and next to some metal, hence, the arc. To diagnose, open "dog house" and run van in the dark, and look for blue arc. To fix, replace spark plug wires. Even if only one is the culprit, you should change them all together. $50 fix.
You will see a white spark because a spark plug produces an electrical arc
bad spark plug wire.
with stuff
A electrical charge from the coil goes through the spark plug wire to the plug were the plug turns it into a arc between the two contacts on the bottom of the plug. that arc ignites the fuel in the cylinder.
'arc' as an electrical spark. Its homnym is 'Ark' and old word for 'ship' ,as in Noah's Ark.
== == Check under the hood at night or in a dark garage for spark arc. Mine would arc or ark from the spark plug wire to the coil on the passenger side of the motor. Spray with WD 40 or silicone to stop the ark then replace the coil and or wires. About $60 for the coil and 50 for wire set. You only get three wires in the set. You don't need the ones on the one side as they are built with the coil. It could be a bad coil pack (black thing above 3 of your spark plugs) I had one go bad and it caused a miss in the engine.
Rephrase the question.
Coil makes electricity and the spark plug wire delivers the electricity to the spark plug where it arc's across the spark plug and ignites the fuel in the cylinder.
Not appropriate earthing condition
Sounds like a plug wire is not completely connected to a plug(s). This will cause an arc that will create this sound.
