Hi guys, Ive got a vl na auto, starts first time, runs and drives well but occassionally revs drop and as i accelerate to keep revs up it stalls. Put in neutral and revs are fine doesnt stall. After stalling starts again right up and drives all day without stalling. While revs are low and accelerating sometimes blows white smoke from the exhaust. Any suggestions on what it could be? Feedback will be welcome. Thanks lads
