2000 Ford F-150, ECM/Inputs/Outputs Scan Data
Posted to the Waveform Library on 10/5/2010

This was taken on a road test about 90 km/h. As I was increasing throttle position ,because I was going up a hill,the 02 sensors were reading rich but the short term fuel trims were adding fuel like the condition was lean. When can this occur?
