GGMan Posted January 16, 2022 Report Share Posted January 16, 2022 Please watch vidoe of trim here: My long term fuel trim at idle hovers at about -10.9% on average and it goes down when I am driving only - it does not change when I press throttle in neutral - it does not chnage when coasting in neutral - it only changes when I am in motion and press throttle. I watched few videos saying the O2 sensor should switch on/off but mine seems to appear to stay at 0.8v majority the time. Any tips on this issue or is this normal for a Subaru? Or what other sensors should I be looking at? Thanks Quote Link to comment Share on other sites More sharing options...
