right ive owned my series 1 for one day and the fun has begun . drove it 50 mile last night with no problems. parked it up last night and it started fine this morning. but after driving it a bit today it decided to start stalling now and again not all the time mainly if id been on boost a bit before say coming to a junction. and then 30 mins ago it stalled and hasnt restarted yet. ive tryed fuel just incase the gauge was reading wrong but still nothing. its pretty standard as far as i no but i have noticed the amal valve looks missing i no my series 2 had one but this engine dosent seem to have one and theres 2 pipes that have been blocked off if any one can give me a clue what could be causing this problem please help
