Hi,
I have 2008 Mazda5 Auto (5 Gears) GS model. I purchased the van with 75,000 miles on it. It is running good but the fuel economy is not that good:
23 MPG: Highway Only
17 MPG: 50% City and 50% Highway
15-16 MPG: City Only
I have an OBDlink-MX and I am monitoring the PID'S of the van and I always noticed that my LTFT are always high positive specially at idle around +(7-14) % and STFT are also positive around +5% except when the van is cold. I have an excel sheet for important sensors reading live as a log file..
Why my van is adding fuel ? Any ides to improve my economy?
Thanks
