the VSS is not an optional sensor
many many many thing key off a working VSS. (in the head)
full engine power will not happen. running and engine in neutral with no load is not like going up hill at speed, not at all.
the ECU will not activate the EGR,
the ECU will not know its moving and will mess up fuel cut mode, and other modes, one is dash pot effect and the other is pumping losses , reduction.
all these waste fuel.
if have cruise option, it be dead.
if car has RWAL it too, many fail.
GOOD LUCK !!!!!
