Bank 1 lean... Take a look at my log ( efi live ) Just finished a head swap and have the car running decent, but I can't seem to track down my lean issue on bank 1. I am adding around 15% on the LTFT on bank 1 and 5-7% on bank 2. I have put in new O2 senosors, checked the coil packs and injectors. Also fogged the intake mani for leaks... I know bank 1 runs a bit leaner, but this seems like too much. The only other think I can think is I have a slight leak at the collector on bank 1, but don't know if enough air could get in to throw it off by this much. If anyone has any ideas please chime in!

This is driving me nuts! I checked for exhaust leaks and put new intake manifold gaskets on along with swapping to 30 lbs injectors. Car runs great but I am still adding pretty heavy fuel on the bank 1 ltft. I know bank 1 will run a bit leaner, but this seems like too much... I attached my latest log... Any ideas would be great
