An ignition setup that eliminates the traditional mechanical distributor, relying instead on multiple ignition coils controlled directly by the engine computer. These systems fire the spark plugs using either a coil-pack setup with waste-spark timing or individual coil-on-plug modules. Removing the distributor eliminates mechanical wear points, prevents moisture-related misfires, and allows for much more precise ignition timing control.

It's a distributorless setup, so check the coil packs first if you're getting a random misfire code.
