LTFT at idle is 0 when the car is cold and hits around +4 when accelerating. When the car is all warmed up, it idles at around +3 and hits +7.2 when accelerating. It seems like I have a vacuum leak, and as the car warms up, the leak gets bigger?
That's because when you put your foot on brake in drive you are putting a load on the engine. At idle STFT and LTFT should within 3% from 0 +/- if the car is operating properly.
