i a-taped my car while just sitting at idel and i noticed this.
What does it mean? what might cause it and what else should i look at?


And what side is bank 1 and bank2?

 

1 = driver side
2 = passenger side

As far as those numbers go, they basically mean your car is "adding" a little fuel @ idle to adjust for a lean condition. You can't really tell much from just idle, drive the car around and get some more readings from different cells and post back.

 

i drove around and look at several cells and in just about all of them the LTTrime for bank 2 is at least 4-12% higher than bank one (witch is around 3-7%)

What should i look at i know my O2 bank 1 sensor threw a code would that efect the LTTrim for bank 2?

 

Does anyone know if this is even nornal or not?
I reset my PCM to try and see if it will re-learn these same LTTrim counts,

I dont know what to check for besides exhauset leaks which i dont have on bank 2 just bank 1

 

I pulled this from the scanmaster page:

"If LBL for a Cell is a lot different than RBL for that Cell, there is something affecting one side of the engine. Example would be a leaky or clogged injector, an exhaust leak or a misfire. This is somewhat subjective, but I would suggest you look for reasons when the difference from right to left is 5 or greater."
