95 eclipse gs pings

i have a 95 eclipse gs. the problem im having is the engine makes a strange vibration after 3rpms. no matter what gear im in. it sounds like a pinging noise. plenty of oil and other than that the car is great. anyone know what it could be?

Check your plugs, it could be just be that some things vibrating in your engine bay or a body panel.
Does it do it in neutral?

yes, every gear above 3rpm

is neutral a gear?
