What causes a spark to go out on a spark plug?
This article focusses on finding the source of misfires caused by the loss of spark. Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
How can I tell if my spark plugs are bad?
Check Engine Light – For many people, the check engine light might be the only sign your engine is having spark plug problems. The ECM is far more sensitive than many drivers and can detect a single cylinder misfire in thousands of good ignitions. Hard Starting – Proper ignition is most difficult when the engine is “cold.”
How do you remove a spark plug from a car?
Use an insulated tool to lift the wire off the plug, one at a time. Now the whole wire and the coil that supplies it is loaded. Use a jumper wire to ground an insulated screwdriver. Gently drag the screwdriver down the length of each spark plug wire, around the coil, and the boots.
What are the symptoms of a narrow spark plug gap?
The duration of the spark has less travel distance, thus not remaining hot enough with sufficient charge to ignite the air-fuel mixture. The symptoms of narrow gap include a noticeable (continuous) cylinder miss, hard starting if all the plugs have narrow gaps, rough idle and engine hesitation.

Can you remove the metal sleeves off of the spark plugs?
Once you wiggle and pull on them you stand a high risk of damaging the spark plug wires! I have the same problem with my 98 dodge ram, there is a metal sleeve that is around the spark plug, there is no way they come off with the plug wire it is not he insulating part of the wire.

Can You reattach spark plugs after replacing them?
The trick is when reattaching the spark plug wires after you replace the plugs is to use lots of dielectric grease on the porcelain of the spark plug body so the plug wire doesn’t bond to the plug. I normally see this problem with cheaper spark plug wire sets. Once you wiggle and pull on them you stand a high risk of damaging the spark plug wires!
