In my case the actual spark plug tube came loose. Also the spark plug tube gaskets my be leaking.
AnswerBadly worn piston rings may cause this. AnswerCommon problem with these engines, actually a cheap fix by a dealership. The sleeves that lead down to the sparkplugs seem to come loose after time and the gaskets fail causing oil to form on the top of your sparkplugs. The early signs are a faint smell of oil when your car warms up but no sign of an oil leak. After a wile the oil will get between the plug wire and the plug itself causing the car to misfire and eventually short out the electronis. To avoid more problems I would recommend taking it to the dealer, where they will pull the valve cover and replace the gaskets and reset your valve cover.. that costs no more than $90-$150, at least when I had mine done at 172,000 miles on my 2001 R/T. The dealership should know about this problem if you describe it to them.if a cylinder is not firing there will be no spark at the spark plug. Carefully twist as you pull the ignition wire out and start the engine. when the wire gets close to the spark plug you should see an arc. This means the cylinder is firing
If you know which cylinder is not getting a spark you should know why. Put a new plug and lead in No. 4. and see what happens.
You can count the number of spark plugs. A four-cylinder engine will have two spark plugs on each side of the engine. A six-cylinder engine will have three spark plugs on each side of the engine.
If they know how, anyone can work on a car.
Well they are hidden by the spark plug boots ;-)
the coil packs are numbered per cylinder
Depending on how many you crossed the engine would fail to run or run very roughly as the spark to the cylinder is not timed correctly
Locate which cylinder is dead, remove the spark plug, if the spark plug is bone dry the injector is probably not working.

Take the cap off the distributor and crank the engine until you see the timing marks line up. When they do, the number one cylinder is at TDC. Now simply look to see which post the rotor on the distributor would be pointing to (remember the cap is off). If you can't find the timing marks, stick a screw driver in the number one cylinder spark plug hole and crank until the piston moves the screw driver out as far as it will go.
Well I have answered this already on another post. But to keep it simple.. Why not do 1 cylinder at a time.. Then what difference does it make for spark plugs.
First things to look at are your distributor cap and rotor, spark plug for that cylinder, and the spark plug wire to that cylinder. If you can't see anything physically wrong with any of those, try switching the spark plug with one from another cylinder, if the misfire moves to the new cylinder, you'll know the plug is bad. If it wasn't the plug, try switching the plug wire with another of the same or similar length, again, if the misfire moves to the new cylinder, you'll know the wire is bad. If that doesn't help, ask "What could cause misfire?" in the Ask box above or click on the link below to that question and answer. There is a lot of information about misfires there.
