First thing to replace is the O2 sensor. On those vehicles their are four. 2 pre cat and 2 post cat converter. Each is different in cord length and connection fitting. Make sure you purchase the correct one for whatever bank you are purchasing. Sensor 1 is pre cat sensor two is post cat. Bank one is a set of 3 cylinders that feed into the exhaust manifold, bank two is the opposite set that feed into the separate exhaust manifold opposite of bank 1.

Bank 2 sensor 1 is right in front of you as you open the hood and look down. It is also known as the Left, Upstream sensor. Japanese built RX of that year uses a different sensor than Canadian built. You need a Denso sensor part# 234-9008. Only use Denso as it is OEM. Double check everything, CEL, etc. Bank 2 sensor 1 Japan built is Denso 234-9008.

Go to the Denso global website and search for your spark plug.
Or else google is your friend.
Good luck!
