The air/fuel ratio sensor has gone bad (basically the O2 sensor). The code P1130 is Bank 1 Sensor 1.
Sensor 1 is before the catalytic converter coming off the exhaust manifold. Bank 1 is which ever side cylinder 1 is on your engine. In this case its a sideways engine and its closest to the firewall.

P0330 and p1130

I wonder if these two codes are related. P0330 could be due to a bad Knock Sensor which might affect the timing thereby causing issues with air/fuel ratio i.e. P1130

P1155 code

Do you only have one o2 sensor? Many cars have two- one in front of catalyst, one behind. The front one is for fuel trim.
Also, that code is for the whole o2 circuit, right? Might need to keep checking. Does your car have a heated o2 sensor? Just another circuit to check, if so. good luck.
Looked at your post again. See where you said o2 sensors. Already changed both, huh? Wow. good luck. Might need a multimeter for resistance test of circuits.

Error code P0430 rear catlytic converter where exactly is this located and what does it look like and estimated price?

just a word of advice there is no sensor that tells you if you need a cat ! that code comes on because of faulty o2 sensors have you changed the 02 sensors yet ? if not change them reset ( clear ) the codes that code will come on a few times just keep resetting or clearing it i have had 2 co workers not listen to me and changed the cat 400-600 dollars and the code just comes back on one guy had the cat changed two times and the code came back after i reset the codes 3 times it stayed off it seems like its preset to come on around 100,000 miles with 02 sensor codes DONT LET THE MECHANIC SELL YOU A CAT hope this helps

Air/flow senor #1 bank made the check engine light come and the code is p1130

P1130 = Air/Fuel Sensor Circuit Range/Performance (Bank 1 Sensor 1).

Chances are the upstream sensor (similar to an O2 Sensor but not compatible) is shot. However, before condemning the sensor, check the circuit (wiring, connector, etc.) for power, ground, etc. If you can, check fuel trims as well.

If it is the sensor, take your VIN# to the dealership for an exact replacement. Be advised...they don't give 'em away.

Good luck and keep us posted.

Code p1130. where is the sensor located on a 2001 rx300 lexus

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.

2000 Lexus RX300 6cyl 3L VVT-i "Engine Codes"!

The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms
