Issue:
A concern has been identified with the operation of the throttle on a number of 1997-98
MY XK8, 1998 MY XJ8 and 1998-99 MY XJR and VDP SC vehicles. Under exceptional
circumstances this concern could cause the engine to cut out, although the engine will
continue to be driven by the road wheels through the transmission and drive the
ancillaries, so there will be no loss of power steering, brakes, air conditioning, etc. The
engine should restart without difficulty once the vehicle has come to a complete
standstill.
