First of all, even though the Issue says Coil Pack, that does not necessarily mean the Coil Pack is Bad. It could be a Loose Connection, it could be a Bad Wire, it can also mean a Bad Spark Plug or fouled Injector but to answer your question...

The Coil Pack is located under the Plastic on top of your Engine and Directly connects to the Spark Plug. If I was you I would Swap the #1 and #3 Coil Packs and see if the Fault Code follows the Coil Pack. If it does then replace the Coil Pack. If it stays with the Cylinder, I would be checking the Connectors, Wires, Injector and Spark Plug.

SOURCE: air conditioner filter toyota corolla 2002

If you have a cabin air filter, it will be located behind the glove box. You need to open the glove box, remove all of the contents, disengage the rod at the right side, and squeeze in on both of the sides towards the center of the box, this defeats the "stops" that keep it from falling out when opened. Let the box door swing down. Right behind the opening left by moving the glove box down & out of the way is the heater box. Look for a rectangular tray, on the box, facing you, pull it straight out towards you. The cabin air filter is located in this tray, if you have one.
No tray = no filter.
Very easy to do this.

Error Code P0351 for a 2005 Toyota Avalon

Possible causes
Faulty Ignition Coil 1
Ignition Coil 1 harness is open or shorted
Ignition Coil 1 circuit poor electrical connection
Faulty Engine Control Module (ECM)

What does this mean? When is the code detected? Each ignition circuit is continuously monitored by the Engine Control Module (ECM). The test fails when the ECM does not receive a valid pulse signal from the ignition coil. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) Lack/Loss of Power Engine may be harder to start Engine hesitation Rough engine idle P0351 TOYOTA Description: The ignition system on the vehicle uses individual ignition coils for each cylinder. The Engine Control Module (ECM) controls each ignition coil operation. The ECM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.

I am change out a direct ingnition coil, which is the c coil?

"C" stands for cylinder #3. Facing the engine from the front of the car, the cylinders go A, B, C, D left to right (i.e., A closest to passenger side). To test you coil, change it with another. Codes are specific to each cylinder. A = P0351, B = P0352, C = P0353, and D = P0354.
