Hello Everyone!

My check engine light came ON and I got diagnosed and the code found was P1130. The mechanic told me that it may be becuase of A/F Ratio sensor Bank1 Sensor1, Spark Plugs, Fuel Injection Cleaning...

I replaced the A/F Sensor(Denso 234-9021) and disconnected the positive terminal of the battery for couple of hours to reset the light... It went OFF but cam back on within 2 miles.... So, then I replaced the spark plugs and did the same thing to reset the light and this time too it came back within 2 miles...

Now I am really frustrated... Anyone has any suggestions for me? Or should I go ahead and get my fuel injection cleaning too?

Thanks!! I appreciate any help.

I have same problem as described above. I thought it was oxygen sensor and just replaced it(bank 1 sensor 1). But the code does not go away. Also, there is a strong smell of gas in the cabin. Any ideas?

BTW: I have 2000 ES300.

Thanks.
