What was the spark plug in cylinder 3?
About a month ago, I had a misfire in cylinder 3. I Decided to just swap out all spark plugs, and only plug that gave me a problem to get out was of course #3. Also replaced coil pack on #3. When I finally got the plug to come loose and pulled it out, a chunk of porcelain was missing.
When to replace spark plugs and coil packs?
This way the misfire moves to other cylinder then you know it was plug and replace it. If misfire still on number one then check for spark and injector pulse and replace injector or coil as needed.

What to do if spark plug falls into cylinder?
Also replaced coil pack on #3. When I finally got the plug to come loose and pulled it out, a chunk of porcelain was missing. I’ve read about that happening before and solutions for it, but I’m afraid I may be past that point. When I knew what happened, I had it towed to a shop to see if I could have them remove the pieces.
What should I do if my spark plug is misfiring?
I suggest first removing and checking the spark plug and swap in a new one or swap with cylinder next to it. This way the misfire moves to other cylinder then you know it was plug and replace it. If misfire still on number one then check for spark and injector pulse and replace injector or coil as needed. Was this answer helpful?

What happens if spark plugs fall out of cylinder?
Either there is damage to the engine or components and the engine will run crappy all the time (if it were to run at all), or it will run just fine all the time where you wouldn’t notice anything had happened. More than likely what is left of the porcelain has passed out of the combustion chamber and is now lodged in the catalytic converter.
How many times does a crank sensor spark?
One wire delivers power in the form of 12 Volts from the PCM. Another delivers Ground. This Ground is provided inside the PCM, too. As the engine turns, a reluctor wheel on the crankshaft activates the crank sensor into creating its On/Off voltage signal 24 times per crankshaft revolution. Activate the 8 COP coils to spark.
