Hey Fellas, I got a VH Commodore with a blue 3.3L. My problem is that it is idling rough, I have checked the manifolds for leaks, checked the timing, checked the Leads, installed new plugs, but all this to no avail. However, through my process of elimination, I have noticed that when cold and at idle, it is just rough, but then as it begins to warm up, the exhaust starts to "fluff" and "pop", my hunch is a burnt exhaust valve. Am I on the right track?

my experience suggests a burnt valve or 2. but do wet and dry compression tests to verify and to identify which cylinders are crook.
