Your Air/Fuel Ratio sensor is failing. It is also called the Bank One sensor. The sensor itself is about $200 from a parts distributor and somewhat more than that at a Lexus parts department. Labor to remove the old sensor and replace it with the new one will also run you several hundred dollars.
If you're mechanically inclined, you can tackle this repair yourself. But you must first determine the exact location of the failed sensor. And be careful not to strip the threads in the manifold when you remove the old sensor.
Let me know if this helps and please rate this solution. lone99star

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.

If it is running perfectly I wouldn't think that you would need to replace the timing belt. You shouldn't need to replace that until 100,000-120,000 miles. I would definitely hold off until now unless you have start having some timing problems. Let me know if you have any other questions. Thanks for rating my response and for using FixYa!

You need 5 quarts in the Lexus RX300. Beware, the RX300 has a history of engine sludge problems (just search the internet for Toyota engine sludge). I would recommend Mobil 1 (this is FULL synthetic) and for viscosity I would recommend 5w-30 in the winter and 10w-30 in the summer. Your manual will verify the viscosity that I have mentioned. You must use good engine oil with this vehicle or else you will have an engine sludge problem and this could cost you a new engine. The RX300 is a wonderful vehicle and very reliable, but it requires some care that you must give it or else it will cost you a lot of money and maybe leave you stranded. For instance, change the oil regularly (no more than 4000 mile intervals) and also change the transmission fluid (no more than 60000 mile intervals). Search online for transmission failures in the RX300 - you'll find that the people who did not get a transmission flush were very sorry!!

Remove 3 - 4 screws on fender cover close to side marker light. Pull fender cover out a bit for you to use your other hand to reach side marker light. By twisting on one direction and here you go the light out. Replace new bulb and replace everything on reverse order.
