p0303 code cylinder 3 misfire
Im going to try to change the spark plug and test the coil, can anyone tell me which plug is cylinder 3? Is this the correct diagram, left one on the passenger side?

You can clear the code and swap the possible bad coil with another and see if the code follows the bad coil. If so, then you'll know that you found the root cause.

Why does that diagram show the oil filler tube and manifold intake facing forward? Canadian car?

The diagram is for a 996 engine. The giveaway is the oil filler tube, throttle body intake, and power steering fluid dipstick are all on the belt side. Here is a 996 pic with the air box removed (the red arrows point to the engine mounts).
