i have a '99 r6. when i press the start button it will turn but not run. it will turn on every now and again and run perfectly fine. but then it will randomly nt turn on. i checked the oil and the oil levels are fine. it was just changed out a week or so ago. sometimes when it's on, it will barely even sputter with the throttle wide open. and i usually have to give it a little gas when starting to make sure it doesn't shut off.. anybody have any thoughts?
