    I was starting my 08 and all was good. it had ran for a few minutes, i turned the idle down and a few minutes later i heard a loud bang and it quit instantly. i didn't try starting again in fear of hurting her more. any ideas as to what it was? my guess is timing chain. Any help is appreciated!
