Hello all, Yesterday set off to Thirsk first real drive since re-map last week, been driving in town all week. All was going well when all of a sudden the car started to kangaroo and stalled at 40mph. Fault cleared and all was well for rest of journey. On way home today did it again and now everytime I start car got to rev for first couple of mins or the engine dies, Ok when you get it up to speed. Also when you back off the throttle it feels a little, juddery/kangarooy. Any advice will be appreciated. Cheers
