so i got my 300 almost 4 months ago. its the SRT-8 addition. love the car but when i want to show off and usually hit the throttle and a redline the engine .. i do this cause i cant get it to rev high enough while driving.. i tried "nuetreal" and w/ the reg brake wont work.. turn off esp .. im still searching the forum for the how to's. so anyway by reving it in park about a dozen times the engine has seized.. RPMs would be 0 no any gear. i would have to push it till i get to where I'm going.. what is this cause of this.. is there a better way to show off. did i break my car?
