Now that is confidence right there....I take it you didn't open the hood, and take the engine cover off when you purchasing....this car is full of sensors, and things can go very wrong...it has a mind of it's own...and sometimes my friend, she loses her mind and does strange things...happy reading thru all the threads, because you are going to have a lot of questions in time to come...

Shouldn't be reving like that, so, if you haven't done anything around the motor lately, I would ask Jerry...but if you have, I would retrace your steps to see if a hose is off somewhere....
