How do you remove a spark plug that fell out of a cylinder?
How do you remove a spark plug that fell out of a cylinder?
You need to use compressed air and blast into the cylinder. This should blow out any pieces of spark plug.
How to replace the rear spark plugs without removing intake?
It all was able to fit while installing and removing the plugs while the extension and plug socket were taped together. This keeps the extension from accidentally pulling out of the spark plug socket. For the left rear plug, it was easier to get access by removing the bracket that holds a large bundle of wires and pushing them out of the way.
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.
Do you have to remove the intake on a GMC Di engine?
You do have to remove the intake on the DI engines (with the aluminum intake; not sure about the plastic one in 13+ models). It’s really easy to do, and once removed you can get to the plugs and coils very easily. Also, if you use the AC Delco iridium plugs, they’re made by NGK, which already has a plating on them so they don’t stick in the head.
Can a ratchet plug be taped to a spark plug?
One thing to do, that I highly recommend, is to tape the spark plug socket to the ratchet extension (~ 6 inches, ~7.5 with spark plug socket). It all was able to fit while installing and removing the plugs while the extension and plug socket were taped together. This keeps the extension from accidentally pulling out of the spark plug socket.

Do you need to pull intake manifold plugs?
The coil pack harness connectors were a little difficult to release because of the little white locks that must be pushed back, and the release tabs are pretty small. But everything is visible and accessible if a little tight. Pulling the intake manifold would definitely provide more room, but I wanted to avoid that if possible.
What causes a spark plug to go bad?
Like others have said, I’d have all the electronics investigated, consider that the bad spark plug you had in the first place might have been damaged by detonation caused by over advanced ignition timing or an excessively lean air/fuel mixture – both of these controlled cylinder by cylinder by the DCM.
