Im scared to even ask this, but sometimes when i've been driving for a bit and i put it to the floor and start hitting 6k+ rpm the engine loses power and makes a very loud noise, similar to it misfiring from coils (I know its not that). Im a little nervous to drive it incase its an apex seal but could it be anything else? its almost like a high pitched fast knocking that it super loud. sounds like there is a hole in the exhast right by the engine, but it only does it when its "slipping".... anyone had this problem before or anyone know what it is? i was looking to sell and ofcourse it started just after i put the car for sale...
thanks
