I'm not sure if this has been asked before or not.
I did a search, but came up empty.
Is there a way to balance out the fuel trims between banks?
Mine are 2-4% higher on one bank?

Great question, but 99.9% sure the answer is no.
According to Mr. Prick (EFILive LTFT expert) it is normal to see a variation. Now, if it a wide discrepancy it might indicate a problem.
Your Bank-Bank LTFT variation sounds totally normal. Why it does it...:confused:.

A difference of 2-4% would seem ok to me...
If you had any airleak (intake, exhaust) then you would get a much higher difference.
If you feel up to it, you could try:
- swapping O2 sensors between banks,
- swapping injectors across banks.
Or, maybe a better thing to do first is get the injectors cleaned if hasn't been done in a long time.

OK, thanks...
The o2 sensors are new, and I don't think interchangeable cuz the plugs are different on each side. The injectors are somewhat new as well.
I think I shall let that one be as is!
