1999 rav 4 Initial code 1135 came up. Replaced Air Fuel sensor with correct Cal. emissions part. 0170 code came up. Checked fuel pressure, replaced filter, temp sensor, cleaned injectors. No change. Replaced ECU, code 0171 gone but code 0125 now present. Checked water temp, 193 degrees. Cleared code with engine/water hot and light comes back with the 0125 code after a few miles. Any ideas?

Let me get this straight, you live in New Jersey, but have a Californian emission spec vehicle?
