    Mine is 2015 Prius 4 and started to knock on morning specially when it is cold, when knocking starts sometimes longer eventually code come out P0304 misfire on cylinder 4, or P0303 cylinder 3, clear the code,sometimes no code if it recover from shaking to normal. I have done all of the Change spark plug ,check fuel injector, clean egr pipe, egr cooler,replace intake manifold gasket, all these, the car run smoothly but the shaking is ON and OFF specially on colder days, by the way live in southern California. I thinking that it's a Toyota problem maybe it the "condensation issue" but I'm still looking how to solve this issue like many of us..hopefully Toyota will come up with a solution.
