I am having the same problem on mine but when it does pop i have a huge power loss like the car isnt getting no petrol,, The wierd thing is when the car is cold it drives fine and no pops or power loss but when the engine is warmer it starts,, nasty though as i nearly had a massive truck plaugh into me whne taking off on a round about the damn thing started poping and cut out on me,,,, Any ideas why this could be guys..
