my BMw 540i M5's engine switches off when idle
I just started having this problem yesterday, and it happened 5 times. Whenever I stop at a traffic light or park somewhere or whenever I dont push on the acceleration enough, the RPM starts goin up and down and eventually it turns the engine of, and I have to restart the car. And its fine when I accelerate.. but it screws up when Im idle.
Im not sure what the hell is going on, I was hoping someone who knew a lot better than I did to help me out. Today I drove it around at low speed and I hadnt had the problem what so ever... Im just afraid it will happen again.. and whats there I could do to fix it?
