Hi guys. Bought an Old X-type recently and on the way home it started behaving strangely. It kind of judders slightly around 1750 rpm (imagine a learner doing a kangaroo start but a lot less severe!) and is constantly in limp mode. Drove at 3k for a while as it had been sitting for about a month and done sub 1000 miles in the last 5 months so thought maybe just needed a run? After a while the coil pack light came on and started to flash which made the car feel better after a while. But then when I took it out an hour later or so it went back to having the same issues. Anyone got any ideas? Plan on doing a service anyway but can't imagine that it will affect that
