Ok here is the story. Went to leave a friends house and car would Crank over but sputter and die and i was making some really weird noises. So after about 15 minutes of trying to start it we roll it down his driveway turn it over and it takes off revs up all th way to 3-grand on its own drove home fine and everything what do you think could be the cause of this? Could i have just flooded it? Thnks for any input

 

Anyone?
