Long term fuel trim question
There's a 6 to 8 % discrepancy between my left and right bank LTFTs. After re-setting the LTFTs to zero, the right bank trims will climb to and settle somewhere between +6 to +8% while my left bank trims will settle somewhere between 0 and +2%.
I've switched the left and right O2 sensors - no change in the LTFTs.
Do these LTFTs indicate a problem? If so, should I be exploring an air leak or fuel delivery issue on the right bank?
Advice from those in the know will be appreciated
