I have end up with check engine light code p0300 p0301p0303 and p0011

i have change the both vvt and only vvt cylinder one broke and I had to dig it out and replaced with dorman.

after ward the check engine p0011 truns on! I replaced and cleared the code, it comes back on again, other I changed the oil after that engine acts funny I check the code it shows misfiring code p0300 p0301p0303 and p0011.

I changed the front and back knock sensors and clear the code, after 20 miles driving it came back on again!

Anyone hav any experience with these 2004 rx330 problems?

With a malfunctioning VVT gear you will get misfire faults so don’t focus on those for now.

The next possible cause is a plugged oil control filter, there is a screen behind a plug in the cylinder head near the VVT oil control valve.

After that the problem would be the camshaft gear.

This is an unusual problem from my experience, is there sludge in the engine?

I have checked the filter and it was clean
