I need help . This morning i woke up and started my s2000 which i bough yesterday. It started fine and i open up engine bay n rev the motor a little. After a few minute the motor seem to rev by itself at 3000 rpm and stayed there. I got scare n shut it off. Now when i crank it up, it wont start at all. It just keep cranking. this is not a good start with my new s2000. It feel likt have a week crank like the battery about to die out but i jumper battery and it is fine..

 

New Battery?

 

sounds like a possible vacuum leak. Please list mods of car if any. or if any recent modifications to the car. Check under the hood for a vacuum line disconnected.
