Can too much oil cause engine vibration?

Too Much Engine Oil As it spins, foam and bubbles accumulate around your crankshaft, hindering the oil from properly lubricating your engine’s internal components. If your engine’s internals isn’t adequately lubricated, friction can develop, resulting in noticeable engine vibrations and shaking.

Can a dirty throttle body cause shaking?
