Hey all hope u might be able to give me an idea to what is causing this problem. i own a vl n/a auto calais and the other day i noticed the rpm was quite low at idle say 600. My car is due for a service and tune soon but i thought what the hey. Then yesterday i was driving to tafe and i was sitting at a set of lights on a slight slope and after about 15 sec of idling it cut out completly. I got it started and thought no big deal but then i tried it on my driveway this morning and it did it again but after that the low rpm remained but my dad and i couldnt get it to cut out agian?? If anyone would have any ideas it would be a great help! Also my car doesnt have enough rpm to keep my car still (it rolls back slowly on a hill in drive)

Check air flow meter, intermittent low/rough idling is often caused by that. It might help if you pull off the plug and clean it.
