RX99inLA

Hi there, I too have an RX 300 with over 100K mileage. I got the P1135 code too, which is the O2 sensor. We also found out that we didn't have enough coolant put into the car. They might be related. Anyways, Autozone estimated $450 for the bank 1 part. :whistles: Well, in the case that I would have to replace the bank 1, can anyone tell me where to buy a cheap one and also how to figure which of the 2(or 3) bank 1's to replace? Thanks much in advance.

Hi guys, Apparently the Oxygen sensor is a common problem for Lexus'. I was wondering if anyone knew where I could buy an oxygen sensor for a cheap price. A guy at Autozone told me that it runs around $450 for a small sensor, and that's just insane. :cries: don't wanna spend that much. any idea's? thanks in advance
