    Daughter car had cat code and lack of power. Burn oil. Had new plugs,coils, and injectors so I took 2 full can of seafoam in oil drove a week. Then remove spark plugs( make sure the Hybrid battery has a decent charge on it!!!!!!) Fill 1/4 of a can of seafoam in each cylinder let sit over night( her car was burning oil like crazy almost all between changes was trying to clear rings drain hole and what was mostly the cause of the oil burning. After 6 hours the seafoam didn't drain then the next day there almost dry. I vacuum out the loose stuff with a tube that fit down there then tryied to start it ran about 45 sec error codes alots of smoke in hooked battery let sit 5 min clean spark plug little wet. The put the Prius in maintenance mode. And ran with 10 x more smoke like it was a bad fire couldn't see anything for over 5 min. Then drove with more power for about 1 day then I had a Missfire error in cyc 3 clean again all it coated them with something so I replaced the new plug with new again huge different in even power but had a ton carbon in the header pipe if I was to do it again I'd unhook the cat with two bolt and 4 hangers so it blows to the ground in stead of clogging the cat
    Worth doing yes not burning oil yet
    Fixing a cat no.
    More power YES
    I drove mostly with a bad cat error waiting for it to get here 2 week but got 43 mpg up from 30's once the cat in and I get some miles all update
    I do it before your neighbor are up it was a lot of smoke. Car starts off the Hybrid battery so AC off don't drain it
    It will be scary but keep it running and if it won't start have to clear all the codes then maintenance mode so it stays on
