Hi,

I have GS430, year 2006.
Removed both front catalytic converters, because i was getting code P0420. Now i sometimes get P0136 code. It means Bank 1 Sensor 2 error.
After catalytic converters were removed, i used spacers on O2 sensors, that go after converters.

Now my car goes into some loop when trying to calibrate fuel/air ratio. On diagnostics program it shows that fuel must be 3% richer, then 5%, 7%, 12%, 15% and drops to 0. Then it repeats.

Should i replace O2 sensor on Bank 1 sensor 2? Maybe spacers should be changed to other brand? Any thoughts? Thanks.

Before buying and spending money on a new sensor that youre unsure about. Why not place the bank 1 into bank 2 swap them around and if you get an error after youve cleared the codes on bank 2 then replace the sensor.

Do you have right angle spacers/ adapters with restriction hole insde. Theres also and capacitor hack been done somewhere to trick the ecu. it spliced into the post o2s

Thank you. Right angle spacers did the job. No errors now.
