I did try leaving the positive cable off overnight to reset things, not sure if that actually works or not. I'm considering re-flashing the ECU. I guess I may have to spend the evening rigging up a smoke machine to double check for vacuum leaks... |
is the trim LTFT +19 or -19 ?
at idle is the measured AFR about 14.7 ? and steady at around 14.7 or is it moving around considerable like to 12 then 15 for example
