Need some HPT help...

[JerzNick]

Tuning noob here, but something seems wrong to me.

1) On the gauge display window, my 02 B1 is literally bouncing up and down, top to bottom constantly, is that normal?
2) Absolutely nothing on the 02 B2 gauge, it just sits at 0...
3) Advance is usually between 25-35, seems high to me, but again, I'm 100% noob.

Thanks in advance for your help guys

*Vid to come soon.

1. That is how o2 sensors work. They go from rich to lean, rich to lean, rich to lean etc. So that explains the top to bottom constant.
2. o2b2 means nothing since its only emissions related so dont worry about that.
3. Advance is the degree of timing. at cruise that seems fine.

To clarify more the more your 02 fluctuates the better if its slow to move up and down your 02 is probably going dead.
As far as advance goes I see up to 45 degrees cruising around wot though is around 22. For me.

Thank you guys for your help... I'm trying to fix this p0036 code... 02 sensor heater, just replaced both sensors and the code keeps coming up, I'm getting terrible mpg's.

Both sensors should move, when they slow down or stop moving something is either very wrong or the sensor is dead.
If the rear has been replaced, and its still not responding it could be several things. It points to a dead cat more than likely. Could also be the harness, exhaust leak ect.

On O2's.

B1S1 is the upstream or front sensor.
B1S2 is the downstream
B2S1 We don't have a B2
B2S2 No B2

No cat installed. Thanks for the info though.
