Ignition coil problems

What are the symptoms of a misfire?

Knocking or pinging sounds

Why might a misfire not trigger a check engine light?

In some cases, a misfire may not trigger a check engine light. This is because the engine’s computer may not be able to detect the misfire, or because the misfire is not severe enough to cause the computer to trigger the light.

What should I do if my car is misfiring and the check engine light is not on?

If your car is misfiring and the check engine light is not on, there are a few things you can do:

Check the spark plugs and spark plug wires.
Check the fuel filter.
Check the air filter.
Check the compression in the cylinders.
Check the ignition coil.

If you are unable to find the cause of the misfire, you should take your car to a mechanic for diagnosis.
