Evening, I was wondering if anybody had come across the same issue that my Focus seems to have developed.

The issue happens usually only after 4 or 5 minutes after start up when cold, I can be pulling up to a set of lights / junction and when I press the clutch instead of a constant idle the revs fluctuate up to around 1500 - 2000 rpm then drop down so low it almost cuts out. Unfortunately a couple of times it has cut out.

The car has only done 30,000 miles and has been serviced on the dot each time.

Any ideas? I've looked on google and others have reported a similar problem ranging back to 10 year old cars but there doesn't seem to be any definitive answer.

Thanks

I'll give it a go cheers!

Will do cheers.
