The FIPL (fuel injection pump lever) sensor may fail. When this sensor goes bad, shifting is erratic and the Check Engine Light should illuminate. Proper adjustment of this sensor (when replacing it) is a must or the problem will continue. See service manuals for proper adjustment of the FIPL sensor.
