The firing order for a 2003 Toyota Highlander with a standard V6 engine is 1-2-3-4-5-6.
The firing order refers to the order in which the cylinders in an engine fire, or ignite the fuel-air mixture. The firing order is important because it determines the power stroke sequence of the engine, which can affect the engine's performance and efficiency.
To determine the firing order of an engine, you can refer to the vehicle's owner's manual, or you can consult a mechanic or a dealership service department. Alternatively, you can also find the firing order by looking at the spark plug wires or by using a diagnostic tool to read the firing order from the engine control module (ECM).

On all cars, the bank 1 is where the first piston is...Your firing order on that car which is the first piston...Buy a chilton or a repair manual for your car and it will tell you which firing order your motor has....Its usually on the right hand side...Passenger side...Rule of thumb if you look at the spark plugs the one closest too you is usually the first piston....Bank 1 is located on the same side as the first piston...I hope this helps...

To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.

The 3.5L (VIN H) engine's unique ignition system has the ignition coils directly over each plug. No spark plug wires are used.
If a coil is replaced on any of the 3.1L, 3.4L or 3.8L engines, it may not be numbered, as is the factory coil. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your guide to reflect how your engine is wired.

I hope help you with this, remember rated this help. Good luck.

I recently starting having this problem also (only code p0305/308). That code means "miss-fire" on #2 cylinder. The #2 cylinder is the nearest cylinder on the right (closest to front of car on drivers side) if you are standing in the front of the car.
