P1130 Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1)
This sensor is the hardest to get at. It is between the cat and the cylinder block on the bank of cylinders closest to the firewall. Not much wiggle room back there.
Sensor will run you about $225 from Toyota, $275 from Lexus, but you may be able to get a Denso sensor on line.
Good luck and hope this helps. keep me posted.

code p 1130 refers to air/fuel ratio sensor circuit /performance malfunction bank 1 sensor 1
talk with a lexus service shop but I feel that all that is a problem heated oxygen sensor (HO2S) in bank 1 exhaust before the cat converter
that heated oxygen sensor reports the gas composition to the ECM so that the air' fuel ratio can be properly adjusted
