Hi Peter, I am also concerned about the fuel trim figures you are seeing as I can't make sense of them in relation to this vehicle. I am assuming you are suggesting that both LTFT and STFT should be at ZERO but LTFT is stuck -100 for some reason pulling the system lean but the STFT is adding 91 trying to make it rich? this would make total trim -9 which would make it run slightly weak? yours in running more than slighty weak therefore some external influence is having an effect?? like an air leak or low fuel pressure? But why would LTFT be so low? unless we have an ECU fault? Unless there is a reset fuel adaptions facility on CLIP that you dont have on your tool? From memmory the ecu/battery disconnection should do it on these but it hasn't in your case? I am just thinkling aloud here, hoppe it helps. Mike
