hi all, i have a 61 plate outback diesel, manual, 122k, basically i bought it from our local auction and have since found out it wont idle when cold, it just cuts out all the time until its fully warmed up, then it drives like a dream, in the paper work it recently had a new clutch, flywheel and exhaust inc a new dpf, i did unplug the temp sensor and it did run a little longer when cold but it did still cut out , has anyone any ideas what it could be, ?
