Probably not the same, but I had very, very intermittent, very, very rough idle occasionally when pulling up at the lights etc Felt like it was going to stall maybe once or twice a week Months going back and forth to Ford to fix under warranty - they never found it, even had the "specialists" looking into it. Could never replicate it when I wanted to Turned out it was an out of balance/dodgy thermo fan - intermittent because they weren't on 90% of the time. Wasn't even a hard drive, just a random cruise to the shop or run on the highway could trigger it though. The blokes at Pitlane finally diagnosed it when I'd all but given up hope - still took a couple of returns to Ford before they finally agreed and put in a new one.
