Hi
I also have this problem.

Mine occurs when hot or cold, and there is no judder, engine man. light comes on for 1 or 2 seconds at start up.

I have changed the MAF sensor and Idle control valve, to cure another problem.

The idling of the car has got worse scince i replaced these two sensors.

Thanks in advance

Theres no engine management light on and its happening when the engine is hot or cold... iv tried to clean the air mass meter with carb cleaner but no joy. any ideas?

Hi

Check the air pipe from the air filter to the carb. Check for splits and that all joints ate air tight.

I just replaced the MAF sensor (halfway between filter and carb) and on the joints was loose and letting in air.
