When i raised the hood i hear a very distinct Click, Click... sound that speeds up then slow down interchangabily (spelling), seems like every time the engine would click, the exhaust would sputter at the same time. Like Click Click Click----followed by the same time from the exhaust Spa Spa Spa.
Thats my cool impression of real audio comming from the engine bay and exhaust
Also car shakes sporadically(spelling) at stop
