help f trim goes high B2 scan in side
I have noticed my stft/ltft bank 2 going high adding to my fuel trims. after several logs it seems occasional but frequent with the only thing I noticed making it repeatable is warmer weather.
so far I have switched my o2's and the problem stayed with bank 2. this morning I switched my fuel injectors from passenger to drivers side and that didn't change anything.
my next guess is exhaust leak or intake leak or wire issue from that o2 sensor.
I have a wideband but it is connected on drivers side. I believe this erratic behavior is what been giving me so much grief trying to get my tune dialed in since I've been watching the drivers side exhaust during tuning. I only noticed this when I went back to watching my o2 sensors.
you can watch my log and see that after a while of driving the fuel trims go off from each other with the bank 2 being a large percentage higher.
