spark plug firing order for Telstar 2.0L

[BlackDalek]

Trying to figure out if the plugs are attached in the correct order.
I can't find a photo anywhere of the correct order.
I can find references on the internet to 1-3-4-2.
I tried connecting them as 1-3-4-2, but perhaps I did it wrong as engine is shaking and making a lot of odd noise.

Attached if a photo of order I used, based on the sequence 1-3-4-2
