Hey Guys amd Girls, Anyone know why the engine would be making a slight tamborine like sound it only does it when idleing, it was idleing low so i ajusted it then i changed all the oils and filters still getting this pesky sound its very faint but its definately there! Had it looked at and i was told it was nothing, but i say nothing was there a few months ago now i have a musical instrument in my engine.
