Which Toyota uses ignition coil 90919-02244?

It is a 3-pin rocker-mount stick coil that fits the Toyota Corolla 2000-2008 in our range. Later Corolla generations use different numbers, so confirm the year and connector.

How do I know if an ignition coil is bad?

Look for a cylinder-specific misfire code (P0301-P0304), rough idle and power loss. Swapping the coil to another cylinder is a reliable test: if the misfire moves with the coil, the coil has failed.

Should I replace all ignition coils at once?

On a high-mileage engine replacing the full set prevents repeat failures, since coils age together. On a low-mileage engine you can replace only the failed coil, and fit new spark plugs at the same time.
