So I've had this car for about 2 months now, since the problems with the other car started. I finally bought a poor man's scan tool (Bluetooth OBD II adapter and Torque) and was playing around with it tonight.
Most things look normal:
Coolant Temp : 186F
O2 Sensor Temp : 950F
MAF : 95 CFM
Intake Vacuum : 35 kPa
Intake Temperature : 5F
STFT : 0
Except...
LTFT : -7 when idle and -13.3 to 13.7 when on the highway... This is constant, I've never seen it get near 0.
Is this something I should be worried about, or just leave it alone?
I also don't have horrible mileage, normally I average between 24 and 28 on the highway.
