Will knocking due to clogged egr disappear with increased rpms/engine speed? Knocking on our Prius is happening when the engine kicks in and goes away when the gas pedal is pressed.
After a few revolutions and TERRIBLE NOISES, it usually gets very quiet. What makes you think about the flywheel in the first place ??
I have replaced the plugs, coils and injectors. I also cleaned the intake manifold and egr pipe. The egr cooler is so clean, I can see daylight through it! I did clean the egr, but it could be malfunctioning. I have an egr valve on order. It will arrive in a couple days.
One other symptom I was reminded off. Slight smell like rotten eggs = exhaust and catalytic converter.
My Prius was using coolant and had the same knocking until the crankshaft blew a hole on the side of the engine
Cause of the problem was a faulty new ignition coil. Replaced with another. Runs smooth. Another code flashed up P261B - water pump bad......what are the odds???
