I replaced the pcv valve in my 00 and no more smoke when I rev it, that’s a win. I think I’ve figured out the issue, even though the fuel trims are in the negatives I think it’s a vacuum leak. It has all the signs but I can’t find it. And the poly motor mounts probably don’t help the shaking. I’m not sure if it’s the intake itself or leaky gaskets. With a vacuum gauge hooked up its pretty steady but moves with the rpms so I don’t think it’s leaky intake gaskets. Maybe intake to plenum or tb gaskets. I wouldn’t be surprised if they are missing, the maf didn’t have one just a layer of rtv.
