Stoned post! ok so you have spark, and its misfiring. fuel and compression tests next.

get an automotive bulb a resistor with the same impedance as the injectors [sevice manual]and some wire, disconnect the injectors and connect each injector wire in turn to the bulb, and crank the engine. light = ok, and vice-versa. Give that its running atall can assume with reasonable safety the ecu is fine, and inconsistent readings here wouldindicate some bad wiring

for the injectors themselves, download the service manual and refer to the fuelling section for the test [you'll need a multimeter]

erm, well theres a special tool which consists of those bits, god knows what they called it though. I'm not into paying excess if i can heath robinson something together. the resistor and you multimeter on continuity mode would do the trick in most cases too.

Is it just my PC or does it sound like that's not missing once the engine actually gathers pace?

You could also try checking the ECU for fault codes.

lo-fi web video doesnt help, but it does seem less pronounced, hence the compression test.
