rattling noise from engine when accelarating
on my 1991 560SEL, i just noticed some rattling noise coming from the engine when I accelarate, particularly when I accelarate hard. there is no noise at start it up nor on idle. also, i do not hear this rattling noise when i press on the gas pedal when car is on park.
anything i should be checking for?
thx,
emmy
