Okay so I have a 2001 LS430 I get a hard start sometimes and when I'm driving and I go full throttle it will backfire through the exhaust and the car will loose power. The cat's have been gutted cause the driver side cat came apart. So p0420 is on no big deal there. I am also getting a bank 2 sensor 2 oxygen sensor code. The car has 252k on it. The idle is perfect on it, it just seems to lack power in normal driving conditions and under full throttle. Any and all help would be fantastic.
