Question about 2000 Lexus RX 300
P1130 A/F Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1). Some possible trouble areas include: open or short in a/f sensor circuit, a/f sensor, air induction system (which it looks like you already checked), fuel pressure, fuel injectors, or your ECM (Engine control Module). I can send you steps to check these but i need your email address cause i can not post them on the internet do to copy right laws.
