How to check and replace the Ignition Coil on Kia Optima?

To check four-cylinder engines (2001-2006), remove coils and connect an ohmmeter to each coil's secondary terminals. Replace any coil with significantly different readings. For a 3-volt power supply, connect two 1.5-volt batteries in series. Connect the power supply to the coil wiring connector and take resistance readings. Replace the coil if readings vary. For V6 engines, disconnect spark plug wires and the primary wiring connector. Check the secondary and primary resistance on the coil's terminals. For 2006.5 and later models, remove coils and check resistance between primary terminals. Replace any coil with significant variations. To replace coils, disconnect the battery cable, remove the engine cover, disconnect the electrical connector, remove mounting bolts, and lift the coil pack.

The Ignition Coil in Kia Optima automobiles works as a vital component in converting the low voltage received from the Kia Optima's battery to the high voltage required for the fire up the air/fuel mixture within the cylinders. This part is made of the primary and secondary coils insulated in an iron core and enclosed in plastic or epoxy. The primary circuit is including the battery and triggering device whereas, the secondary circuit is the high tension lead and spark plug wires. Ignition systems include the distributor ignition, the coil on plug and wasted spark ignition; they all have different ways through which they apply voltage on the spark plugs. There are cases where the ignition coil will fail and lead to a no-start scenario or extremely poor idle, which in essence mandates for replacement.
