i drive a 99 m3 evo, over the past couple of weeks i have accured a problem. when driving the car most days u can put your foot down and the power is all there, other days u can do it, it feels like u only get half the power. i have used 98 octaine fuel since i have had it. but its an intermitant problem the majority of the time its fine. any ideas would be very gratful. cheers:cry:
