Sudden vibrations + engine uneven, help!

[Stressball]

Hi all,

This afternoon while waiting at a roundabout for traffic to let me in, the car began to have a really uneven, lumpy idle. The vibrations could be felt through the entire car, accelerating and steering both vibrate the entire cabin a hell of a lot. The uneven engine note seems to disappear at higher RPM, but comes back when it is dropped again. I've got two sound clips of it, from both the exhaust pipe end of the car and from under the bonnet. They are streaming audio.

Any help in finding out what's causing this would be very greatly appreciated!

Probably ignition related - check the simple things first - pop the bonnet and run the engine in the dark and watch for sparks from plug leads and the coils. Also when engine stopped make sure all plug leads are fully pushed onto plugs and coils. Then read the codes.
Good Luck.
