An internal combustion engine having electronic throttle control includes an air assisted injector system for directing a controlled amount of air directly to the combustion chamber without passing through the throttle body. A method of diagnosing faults in the air assisted injector system is disclosed. The method comprises the steps of measuring the airflow entering an intake of the electronic throttle of the engine at idle speed with the air assisted injector system operating at a first rate of airflow, turning the air assisted injector system off, measuring the airflow entering the intake of the electronic throttle of the engine at idle speed with the air assisted injector system off, and generating an error signal as a function of the two measured values.

The harvester as set forth in claim 1 wherein the upright feeder comprises vertically spaced finger wheels having fingers curved rearwardly relative to direction of rotation of the feeder. 5. The harvester as set forth in claim 1 including feeder grid structure supported adjacent the upright feeder, wherein the upright feeder comprises fingers projecting through the feeder grid structure adjacent the second row receiving area. 6. The harvester as set forth in claim 5 wherein the harvesting drum includes projecting spindles and further including a spindle grid offset from the feeder grid structure, the spindle grid and feeder grid structure defining a laterally extending plant path for the second row of plants. 7. The harvester as set forth in claim 6 wherein the spindle grid limits contact of the spindles with the second row of plants until the second row is moved laterally towards alignment with the first row of plants. 8. The harvester as set forth in claim 5 further including rib structure located on a side of the second row opposite a feeder side of the row to assist in maintaining plants in the second row in contact with the feeder. 9. A harvester adapted for forward movement over a field for harvesting at least first and second rows of plants transversely spaced a preselected distance or less apart including a row unit having a width approximately equal to or greater than the preselected distance, the row unit including first and second row receiving areas, an upright harvester drum supported for rotation at a drum speed adjacent the first row receiving area for removing crop from first row of plants, an upright feeder rotatable about an upright axis adjacent the second row receiving area and forwardly of the harvester drum, drive structure rotating the upright feeder to gently direct the second row of plants transversely towards the first row of plants, a cutter supported adjacent the lower end of the upright feeder for cutting the second row of plants, and including grid structure guiding the second row towards the first row and maintaining the second row out of contact with the harvester drum until the second row is generally aligned with the first row receiving area. 10. A harvester adapted for forward movement over a field for harvesting at least first and second rows of plants transversely spaced a preselected distance or less apart including a row unit having a width approximately equal to or greater than the preselected distance, the row unit including first and second row receiving areas, an upright harvester drum rotatably supported adjacent the first row receiving area for removing crop from first row of plants, an upright feeder rotatable about an upright axis adjacent the second row receiving area and forwardly of the harvester drum, a driveable cutter for severing the second row of plants, drive structure rotating the upright feeder and driving the cutter to sever and direct the second row of plants transversely towards the first row of plants, and grid structure defining a transversely extending path for the second row of plants, the grid structure including a drum grid separating the harvesting drum from the second row of plants until the second row is moved laterally into the first row of plants and a feeder grid providing contact of the feeder with the second row of plants as the second row is moved laterally towards the first row. 11. The harvester as set forth in claim 10 wherein the cutter is mounted for rotation about the upright axis and connected to the drive structure for rotation at a speed greater than the speed of the upright feeder. 12. The harvester as set forth in claim 10 wherein the harvesting drum comprises spindles projecting into the first row of pl
