Using fuel trim as a diagnostic tool can to improve vehicle engine power and economy is the focus of this AVI video (LBT-177 Fuel Trim Diagnostics with Jim Wilson). Included in Wilson’s discussion to achieve this goal, which can lead to selling more fuel injection work, is the part fuel sensors and catalytic converters play in fuel trim diagnosis. Moreover, he details the affect of high mileage, dirty injectors, O2 sensors and coking on short-term fuel trim. To make this diagnostic approach as practical as possible, Wilson provides the information on where to find the needed service data, as well as setups and many helpful service tips.
