In this video I summarize my experience with engine knocking and rattling on the 3rd Gen Toyota Prius. I talk about when the knocking problem first appeared and what I did to repair it. I give my recommendations on how I think other folks should approach the problem from checking your spark plugs to cleaning your EGR system. With this knowledge you will be able to get to the root cause of the issue quicker and spend less time on unnecessary repairs.
