At idle engine load should be arround 0.3
afr generally arround 14.7 once warmed up at idle
ltft will vary a bit depending on intake air temps fuel ethhanol percent ect but should be less than 10% usually arround +\-5% in most cases ,if long termm fuel trim is high like 15 to 20% usually an indication something is wrong
short term fuel trim will vary widly with throttle application this is normal
commanded afr and afr should follow each other under load
