The tachometer sensor may fail on Ford F-250

The tachometer sensor may fail; if the tachometer needle jumps around and the transmission has harsh shifts or does not upshift, this sensor should be checked. This sensor is mounted in a cover at the front of the motor.

When at idle tach drops to zero then when accelerator is pressed it jumps to appropiate engine speed

This I think is also causing the engine to hover when at a constant speed.
