hey - recently I noticed a bumpy idle which i didn't really take any notice of but over the past few weeks it's got a fair bit worse. I've got 72k on the clock so i'm due a service in around 5k miles. On a cold start it takes a couple of seconds to startup and then the rough idle begins. Usually first thing in the morning and when i've finished work. I noticed it got worse after a round trip towards Manchester which clocked up around 400 miles but i'm by no means a rough driver - especially on long journeys.
Any ideas ??
